Add volatiles for x86-64 bits/mathinline.h
[BZ #14053]
GCC 4.7 might remove consecutive calls to e.g. lrintf since
the assembler instructions are the same and GCC does not know
that the result is different depending on the rounding mode. For
SSE instructions, the control register is not available so there
is no way to inform GCC about this. Therefore the asms are marked
as volatile.
