I believe that the code generator now properly handles dead basic blocks. If not,
...
this is a bug, and should be fixed.

Fix a regression from r1.224. In particular, codegen a cast from double ->
...
float as a truncation by going through memory. This truncation was being
skipped, which caused 175.vpr to fail after aggressive register promotion.

map on the side, Instruction no longer has to be Annotable. This reduces

Do not find these ugly sparc-specific objects by using the annotation API on

instructions. Instead, keep a map of instructions -> MCFI objects in the
