The builtin byteswap routines cause critical failure on AArch64 when built with the Android toolchain.
I didn't experience this issue when building for Linux using a local qemu chroot.
Seems to be only an issue with the Android toolchain when building AArch64.
Use our generic version instead.
If the inputs are both float singles, and the top half is known to be identical
to the bottom half, we can use packed arithmetic instead of scalar to skip
the movddup.
This is slower on a few rather old CPUs, plus the Atom+Silvermont, so detect
Atom and disable it in that case.
Also avoid PPC_FP on stores if we know that the output came from a float op.
When we cleaned up the code to calculate the shm_position and total_mem
in one step, we sometimes skipped over certain views because they were
Wii-only. When looking at the total memory, we'd look at the last field,
whether or not it was skipped. Since Wii-only fields are the last view,
this meant that the shm_position was 0, since it was skipped, causing us
to map a 0-sized field. Fix this by explicitly returning the total size
from MemoryMap_InitializeViews.
Additionally, the shm_position was being calculated incorrectly because
it was adding up the shm_position *before* the mirror, rather than after
it. Fix this by adopting a scheme similar to what we had before.
The code to calculate the offsets into the SHM file wasn't properly
respecting the skip flags, causing it to calculate offsets beyond
the end of the SHM file.
This code was ported from out_ptr, which was a double-pointer, and
wanted to double-check that the proper arena was actually allocated.
When I ported it to store the pointer directly in the view regardless
of whether out_ptr was non-NULL, I got confused here and instead
caused the code to only free the arena if the first byte was non-zero.
