This checkin represents some cleanup of the backend, implementing the following things:
1. The TargetMachine structure is free to decide the process a particular target uses to generate code.
2. All of the gooee details of the sparc backend are now localized in the lib/CodeGen/TargetMAchine/Sparc directory. The Sparc.h file that is globally visible is just a stub.
3. The Sparc.h file that esxists now will dissapear entirely someday when we have multiple backends chosen by a factory of some sort.

-Scheduling guidelines for SPARC IIi:
-
-I-Cache alignment rules (pg 326)
--- Align a branch target instruction so that it's entire group is within
- the same cache line (may be 1-4 instructions).
-** Don't let a branch that is predicted taken be the last instruction
- on an I-cache line: delay slot will need an entire line to be fetched
--- Make a FP instruction or a branch be the 4th instruction in a group.
- For branches, there are tradeoffs in reordering to make this happen
- (see pg. 327).
-** Don't put a branch in a group that crosses a 32-byte boundary!
- An artificial branch is inserted after every 32 bytes, and having
- another branch will force the group to be broken into 2 groups.
-
-iTLB rules:
--- Don't let a loop span two memory pages, if possible
-
-Branch prediction performance:
--- Don't make the branch in a delay slot the target of a branch
--- Try not to have 2 predicted branches within a group of 4 instructions
- (because each such group has a single branch target field).
--- Try to align branches in slots 0, 2, 4 or 6 of a cache line (to avoid
- the wrong prediction bits being used in some cases).
-
-D-Cache timing constraints:
--- Signed int loads of less than 64 bits have 3 cycle latency, not 2
--- All other loads that hit in D-Cache have 2 cycle latency
--- All loads are returned IN ORDER, so a D-Cache miss will delay a later hit
--- Mis-aligned loads or stores cause a trap. In particular, replace
- mis-aligned FP double precision l/s with 2 single-precision l/s.
--- Simulations of integer codes show increase in avg. group size of
- 33% when code (including esp. non-faulting loads) is moved across
- one branch, and 50% across 2 branches.
-
-E-Cache timing constraints:
--- Scheduling for E-cache (D-Cache misses) is effective (due to load buffering)
-
-Store buffer timing constraints:
--- Stores can be executed in same cycle as instruction producing the value
--- Stores are buffered and have lower priority for E-cache until
- highwater mark is reached in the store buffer (5 stores)
-
-Pipeline constraints:
--- Shifts can only use IEU0.
--- CC setting instructions can only use IEU1.
--- Several other instructions must only use IEU1:
- EDGE(?), ARRAY(?), CALL, JMPL, BPr, PST, and FCMP.
--- Two instructions cannot store to the same register file in a single cycle
- (single write port per file).
-
-Issue and grouping constraints:
--- FP and branch instructions must use slot 4.
--- Shift instructions cannot be grouped with other IEU0-specific instructions.
--- CC setting instructions cannot be grouped with other IEU1-specific instrs.
--- Several instructions must be issued in a single-instruction group:
- MOVcc or MOVr, MULs/x and DIVs/x, SAVE/RESTORE, many others
--- A CALL or JMPL breaks a group, ie, is not combined with subsequent instrs.
---
---
-
-Branch delay slot scheduling rules:
--- A CTI couple (two back-to-back CTI instructions in the dynamic stream)
- has a 9-instruction penalty: the entire pipeline is flushed when the
- second instruction reaches stage 9 (W-Writeback).
--- Avoid putting multicycle instructions, and instructions that may cause
- load misses, in the delay slot of an annulling branch.
--- Avoid putting WR, SAVE..., RESTORE and RETURN instructions in the
- delay slot of an annulling branch.

+Scheduling guidelines for SPARC IIi:
+
+I-Cache alignment rules (pg 326)
+-- Align a branch target instruction so that it's entire group is within
+ the same cache line (may be 1-4 instructions).
+** Don't let a branch that is predicted taken be the last instruction
+ on an I-cache line: delay slot will need an entire line to be fetched
+-- Make a FP instruction or a branch be the 4th instruction in a group.
+ For branches, there are tradeoffs in reordering to make this happen
+ (see pg. 327).
+** Don't put a branch in a group that crosses a 32-byte boundary!
+ An artificial branch is inserted after every 32 bytes, and having
+ another branch will force the group to be broken into 2 groups.
+
+iTLB rules:
+-- Don't let a loop span two memory pages, if possible
+
+Branch prediction performance:
+-- Don't make the branch in a delay slot the target of a branch
+-- Try not to have 2 predicted branches within a group of 4 instructions
+ (because each such group has a single branch target field).
+-- Try to align branches in slots 0, 2, 4 or 6 of a cache line (to avoid
+ the wrong prediction bits being used in some cases).
+
+D-Cache timing constraints:
+-- Signed int loads of less than 64 bits have 3 cycle latency, not 2
+-- All other loads that hit in D-Cache have 2 cycle latency
+-- All loads are returned IN ORDER, so a D-Cache miss will delay a later hit
+-- Mis-aligned loads or stores cause a trap. In particular, replace
+ mis-aligned FP double precision l/s with 2 single-precision l/s.
+-- Simulations of integer codes show increase in avg. group size of
+ 33% when code (including esp. non-faulting loads) is moved across
+ one branch, and 50% across 2 branches.
+
+E-Cache timing constraints:
+-- Scheduling for E-cache (D-Cache misses) is effective (due to load buffering)
+
+Store buffer timing constraints:
+-- Stores can be executed in same cycle as instruction producing the value
+-- Stores are buffered and have lower priority for E-cache until
+ highwater mark is reached in the store buffer (5 stores)
+
+Pipeline constraints:
+-- Shifts can only use IEU0.
+-- CC setting instructions can only use IEU1.
+-- Several other instructions must only use IEU1:
+ EDGE(?), ARRAY(?), CALL, JMPL, BPr, PST, and FCMP.
+-- Two instructions cannot store to the same register file in a single cycle
+ (single write port per file).
+
+Issue and grouping constraints:
+-- FP and branch instructions must use slot 4.
+-- Shift instructions cannot be grouped with other IEU0-specific instructions.
+-- CC setting instructions cannot be grouped with other IEU1-specific instrs.
+-- Several instructions must be issued in a single-instruction group:
+ MOVcc or MOVr, MULs/x and DIVs/x, SAVE/RESTORE, many others
+-- A CALL or JMPL breaks a group, ie, is not combined with subsequent instrs.
+--
+--
+
+Branch delay slot scheduling rules:
+-- A CTI couple (two back-to-back CTI instructions in the dynamic stream)
+ has a 9-instruction penalty: the entire pipeline is flushed when the
+ second instruction reaches stage 9 (W-Writeback).
+-- Avoid putting multicycle instructions, and instructions that may cause
+ load misses, in the delay slot of an annulling branch.
+-- Avoid putting WR, SAVE..., RESTORE and RETURN instructions in the
+ delay slot of an annulling branch.
