MS name mangling supports cache for first 10 distinct function
arguments. The error was when non cached template type occurred twice
(e.g. 11th and 12th). For such case in code there is another cache
table TemplateArgStrings (for performance reasons). Then one '@'
character at the end of the mangled name taken from this table was
missing. For other cases the missing '@' character was added in
the call to mangleSourceName(TemplateMangling) in the cache miss code,
but the cache hit code didn't add it.
This fixes a regression from r362560.

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.

They don't seem to be used for back references, presumably because a
function template is unlikely to reoccur, while a class template name
may reoccur as a type.
This fixes a mangling issue for llvm::hash_combine() in Hashing.h.

I've added an extra FileCheck pass for that with an extra "CURRENT" prefix.
I've carefully chosed the CURRENT/CORRECT prefixes so they
a) are self-descriptive
b) have the same length so the mangling between the current and the correct version is obvious
Feel free to ask me to change the prefixes if you know a better alternative.
