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.

Summary:
Enforce the rule in C++11 [temp.mem]p2 that local classes cannot have
member templates.
This fixes PR16947.
N.B. C++14 has slightly different wording to afford generic lambdas
declared inside of functions.
Fun fact: Some formulations of local classes with member templates
would cause clang to crash during Itanium mangling, such as the
following:
void outer_mem() {
struct Inner {
template <typename = void>
struct InnerTemplateClass {
static void itc_mem() {}
};
};
Inner::InnerTemplateClass<>::itc_mem();
}

Compute mangling numbers for externally visible local variables and tags.
Change the mangler to consistently use discriminators where necessary.
Tweak the scheme we use to number decls which are not externally visible
to avoid unnecessary discriminators in common cases now that we request
them more consistently.

As it turns out, the NoFunction bit for local class mangling needed to be
propagated into more places. r185450 turned what used to be an incorrect
mangling into an assertion.

fix a code gen crash. This is WIP as not
all ABI cases are covered (there is a FIXME to
this effect). Fixes radar 7696748.
