Pierre Gousseau 5ff99f6b0a [X86] Make sure we do not clobber RBX with mwaitx when used as a base 
pointer.

mwaitx uses EBX as one of its argument.
Using this instruction clobbers RBX as it is defined to hold one of the
input. When the backend uses dynamically allocated stack, RBX is used as
a reserved register for the base pointer.

This patch is adapted from @qcolombet patch for cmpxchg at r263325.

This fixes PR43528.
