Add proper __sync_*() intrinsics for MIPS.
To make <stdatomic.h> work on MIPS (and ARM) using GCC, we need to provide implementations of the __sync_*() functions. I already added these functions for 4 and 8 byte types to libcompiler-rt some time ago, based on top of <machine/atomic.h>. Unfortunately, <machine/atomic.h> only provides a subset of the features needed to implement <stdatomic.h>. This means that in some cases we had to do compare-and-exchange calls in loops, where a simple ll/sc would suffice. Also implement these functions for 1 and 2 byte types. MIPS only provides ll/sc instructions for 4 and 8 byte types, but this is of course no limitation. We can simply load 4 bytes and use some bitmask tricks to modify only the bytes affected. Discussed on: mips, arch Tested with: QEMU
