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.

Douglas Gregor 61226d3fcf When determining whether we can make a declaration into a global 
constant, also consider whether it's a class type that has any mutable
fields. If so, it can't be a global constant.

Douglas Gregor 2d1c055eba In C++, allow us to emit a global as 'constant' even if it has class 
type, so long as it is known to have a constant initializer and the
class type is a POD class. Fixes <rdar://problem/9306265>.

Alexis Hunt aecc45cb3c Mangle static variables with an extra name to distinguish them from non-static variables in the same TU. 
Fixes PR5966 for real this time; also reverts r92911, which had a incorrect fix.

Daniel Dunbar 8fbe78f6fc Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'. 
- This is designed to make it obvious that %clang_cc1 is a "test variable"
   which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
   can be useful to redefine what gets run as 'clang -cc1' (for example, to set
   a default target).
