CMake: Add disabling optimization on MSVC8 and MSVC10 as workaround for some files in Target/ARM and Target/X86.

autoconf: Add --disable-embed-stdcxx to suppress linking libstdc++.a into llvm.dll with --enable-shared on Cygming.

Cygwin has stdc++.dll in it's distribution, and we can assume distro's stdc++.dll might be available.

This would be needed to build pthread*.dll-free distribution on recent MinGW-MSYS distros.

like 6 is a fixed point of that and so the previous tests were OK :-)

it relies on assumptions that may not be true in the future.

Multiple SPARC backend fixes: added Y register; updated select_cc, subx, subxcc defs/uses; 
and fixed CustomInserter.

This was done for label, void, floating point, x86mmx, metadata,
just not integer.
