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). --HG-- extra : convert_revision : eac69efb28cce7b48035480d8b7cb004782969f4
