[BOLT] Fix instrumentation problem with floating point

If BOLT instrumentation runtime uses XMM registers, it can interfere
with the user program causing crashes and unexpected behavior. This
happens as the instrumentation code preserves general purpose registers
only.

Build BOLT instrumentation runtime with "-mno-sse".
