[X86] Use bundle for CALL_RVMARKER expansion.
This patch updates expandCALL_RVMARKER to wrap the call, marker and
objc runtime call in an instruction bundle. This ensures later passes,
like machine block placement, cannot break them up.
On AArch64, the instruction sequence is already wrapped in a bundle.
Keeping the whole instruction sequence together is highly desirable for
performance and outweighs potential other benefits from breaking the
sequence up.
