Hans Wennborg c9bd88e681 Remove the -cxx-abi command-line flag. 
This makes the C++ ABI depend entirely on the target: MS ABI for -win32 triples,
Itanium otherwise. It's no longer possible to do weird combinations.

To be able to run a test with a specific ABI without constraining it to a
specific triple, new substitutions are added to lit: %itanium_abi_triple and
%ms_abi_triple can be used to get the current target triple adjusted to the
desired ABI. For example, if the test suite is running with the i686-pc-win32
target, %itanium_abi_triple will expand to i686-pc-mingw32.

Hans Wennborg 9125b08b52 Update tests in preparation for using the MS ABI for Win32 targets 
In preparation for making the Win32 triple imply MS ABI mode,
make all tests pass in this mode, or make them use the Itanium
mode explicitly.

Lang Hames a930e7131c When used in a compound expression FP_CONTRACT should proceed all explicit 
declarations and statements. Emit an error if the FP_CONTRACT is used
later in a compound statement.

Lang Hames 5de91cc35f Add FP_CONTRACT support for clang. 
Clang will now honor the FP_CONTRACT pragma and emit LLVM
fmuladd intrinsics for expressions of the form A * B + C (when they occur in a
single statement).
