x86-64 SIMD: Optimize argument collection

Browse Source 
Expand collect_args/uncollect_args macros so that the number of
arguments can be specified.  This prevents unnecessary push and mov
instructions.

NOTE: On Windows, the push/pop of xmm6 and xmm7 had to be moved to the
other end of the macro to ensure that rsp is aligned on a 16-byte
boundary.
