Optimization fixes
Two primary fixes. First, the save/restore mechanism for FP callee saves
was broken if there were any holes in the save mask (the Arm ld/store
multiple instructions for floating point use a start + count mechanism,
rather than the bit-mask mechanism used for core registers).
The second fix corrects a problem introduced by the recent enhancements
to loading floating point literals. The load->copy optimization mechanism
for literal loads used the value of the loaded literal to identify
redundant loads. However, it used only the first 32 bits of the
literal - which worked fine previously because 64-bit literal loads
were treated as a pair of 32-bit loads. The fix was to use the
label of the literal rather than the value in the aliasInfo - which
works for all sizes.
