GCC Update

Fixes a code generation bug where a v_elseif could be active on a vector lane even when an earlier clause had done so. This primarily affected conditions containing a <= b or !(a > b)

Compiler fixes

• The workaround for Wormhole's read-after-write hazard was incomplete and could miss cases. The hazard occurs when a wider read follows a narrow write -- the read could occur before the write. In this case an intervening narrow write would cause the workaround to be omitted.
• Synthesis of sfpload or sfpstore instructions with non-immediate addresses on Blackhole would result in incorrect instructions being generated.

Synth instruction fix

Fixes a bad assembly code generation issue, which results in errors such as:

/tmp/ccvUeC4h.s:7322: Error: illegal operands `li 10,1048576'
/tmp/ccvUeC4h.s:7323: Error: illegal operands `xor 10,10,a2'

Synth-renumber optimization fix

Fixes a compiler crash in the synth_renumber optimization pass

Replay Optimization Fix

Fixes an internal compiler error in the replay optimization pass

Compiler Update

• Reimplement non-immediate operand handling. Fixes some code generation bugs and implements some optimizations.
• Various cleanups
