Upgrade the ugly darwin 64-bit bswap idiom (bswap %eax / bswap %edx /

xchgl %eax, %edx) to llvm.bswap.i64. This compiles:
long long test2(long long A) {
return _OSSwapInt64(A);
}
to:
_test2:
movl 8(%esp), %eax
movl 4(%esp), %edx
bswapl %eax

ret
instead of:
_test2:
movl 8(%esp), %edx
movl 4(%esp), %eax

Fixed mingw\cygwin linkonce linkage once again.
...
Added workaround for linker bug with linkonce sections.
Changed sections prefix to allow linker merge them
(PE loader doesn't like too much long-named sections :) )
All of this unbreaks libstdc++ on mingw32 allowing (small)
programs to be compiled, linked and run.
