A couple of FP-related fixes (prompted by Adam having trouble
running SPEC FP codes).
arch/alpha/isa_desc:
Don't warn about non-standard trapping modes more than
once per static instruction. (Had the flag to suppress
these but forgot to check it!)
build/SConstruct:
Add USE_SSE2 option to enable compiling w/SSE2 (important
for getting IEEE-compliant FP on x86).
