JIT: Fix for lightweight assembler retry mechanism.
Removed a special path in the assembler that took in sideband
info on some instructions and used it to modify pc-relative load
addresses. This mechanism (used in some older chaining cells) is
no longer needed, and was causing a problem for the new lightweight
assembler retry mechanism.
