aad1b6786e x86inc: Add some additional cpuflag relations 
Simplifies writing assembly code that depends on available instructions.

LZCNT implies SSE2
BMI1 implies AVX+LZCNT
AVX2 implies BMI2

d991b3e8a8 x86inc: Remove argument from WIN64_RESTORE_XMM 
The use of rsp was pretty much hardcoded there and probably didn't work
otherwise with stack_size > 0.

cd4ca82459 x86inc: Prefer r14/r15 over r12/r13 on x86-64 
Due to a peculiarity in the ModR/M addressing encoding, the r12 and r13
registers sometimes requires an additional byte when used as a base register.

r14 and r15 doesn't have that issue, so prefer using them.

406e0ddc0b x86inc: Fix call with memory operands 
We overload the `call` instruction with a macro, but it would misbehave when
the macro argument wasn't a valid identifier. Fix it by explicitly checking
if the argument is an identifier.

7627df15d4 x86util: import MOVHL macro 
Originally committed to x264 in 1637239a by Henrik Gramner who has
agreed to re-license it as LGPL.  Original commit message follows.

    x86: Avoid some bypass delays and false dependencies

    A bypass delay of 1-3 clock cycles may occur on some CPUs when transitioning
    between int and float domains, so try to avoid that if possible.

cd09e3b349 x86inc: Avoid using eax/rax for storing the stack pointer 
When allocating stack space with an alignment requirement that is larger
than the current stack alignment we need to store a copy of the original
stack pointer in order to be able to restore it later.

If we chose to use another register for this purpose we should not pick
eax/rax since it can be overwritten as a return value.
