Stenzek ecbe239c0b Common: Use Mach VM routines for memory mapping 
MacOS does not support an equivalent of MAP_FIXED_NOREPLACE via mmap(),
which means that our usage for allocating PCSX2's memory map is not
thread-safe.

Stenzek c7a21a60cf GS: Improve vsync mode selection 
All games use mailbox/triple buffering. Except when you enable sync to
host refresh, in which case FIFO/double buffering is used.

This means vsync enabled will ever tear, but at the same time, never
drop to 30fps on a missed frame due to frame rate differences.

To have the "best of both worlds", you should enable vsync and sync to
host refresh. Previously, this resulted in additional input lag, since
the host vsync would drive the EE frame timing. Now, this behaviour is
disabled by default, unless you enable "Use Host VSync Timing".

Stenzek e24d97bbe4 Common: Don't use MAP_FIXED on Linux 
MAP_FIXED will clobber any existing memory mapping, and is not safe
to use in a multi-threaded environment. Whether we like it or not,
we are a multi-threaded environment, because Qt initializes before
we get to main(), so it's already too late to safely use MAP_FIXED
by the time we get there.

Use MAP_FIXED_NOREPLACE instead. This is how MAP_FIXED should have
behaved from the beginning.

Obviously this means you'll need Linux 4.17+ and a semi-recent libc
to use PCSX2 now. But if you're running a 6 year old unsupported
kernel, you have bigger problems.

Fixes "random" startup crashes.

Connor McLaughlin 00bcb4cf02 System: Revamp memory allocation 
Guest memory is now mapped into a shared memory/file mapping, for use
with fastmem.

64-bit and 128-bit arguments are passed by register/value instead of by
reference/address.

LDL/LDR/SDL/SDR now use 64-bit GPRs instead of SSE.
