The problem was that we were asserting the we never added an empty class
to the same offset twice. This is not true for unions, where two members, empty
or not, can have the some offset.

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.

This is a 28% speedup running StrongPHIElimination on 403.gcc.

doing a release build.
