In compiler-rt, a few assembler implementations for i386 floating point
conversion functions use SSE2 instructions, but these are not guarded by
#ifdef __SSE2__, and there is no implementation using general purpose
registers.  For these functions, use the generic C variants instead,
otherwise they will cause SIGILL on older processors.
