Fix this test to account for a movl $0 being emitted as an xor now,
and convert it to FileCheck.

If SSE2 is available, x86 should pass first 3 f32/f64 arguments in XMM registers for fastcc calls.

For whatever the reason, x86 CallingConv::Fast (i.e. fastcc) was not passing scalar arguments in registers. This patch defines a new fastcc CC which is slightly different from the FastCall CC. In addition to passing integer arguments in ECX and EDX, it also specify doubles are passed in 8-byte slots which are 8-byte aligned (instead of 4-byte aligned). This avoids a potential performance hazard where doubles span cacheline boundaries.
