Add generic __bswap[ds]i2 implementations
Summary:
In FreeBSD we needed to add generic implementations for `__bswapdi2` and
`__bswapsi2`, since gcc 6.x for mips is emitting calls to these. See:
https://reviews.freebsd.org/D10838 and https://reviews.freebsd.org/rS318601
The actual mips code generated for these generic C versions is pretty
OK, as can be seen in the (FreeBSD) review.
I checked over gcc sources, and it seems that it can emit these calls on
more architectures, so maybe it's best to simply always add them to the
compiler-rt builtins library.
