The alias pseudos need cleaned up for size suffix handling, but this gets
the basics working. Will be cleaning up and adding more.

mutable member and a constant initializer. We'd previously promoted such
variables to global constants, resulting in nasal demons if the mutable member
was modified.

This is only a temporary fix. The subtle interplay between isConstantInitializer
and CGExprConstant is very bug-prone; there are some other issues in this area
which I will be addressing in subsequent, more major reworking of this code.

When we're passing a vector with an illegal type through memory on x86-64, use byval so we're sure the backend does the right thing.  Fixes va_arg with illegal vectors and an obscure ABI mismatch with __m64 vectors.

will allow us to represent a process/thread ID using a pointer for the OS
plug-ins where they might want to represent the process or thread ID using
the address of the process or thread structure.

It was getting ignored after r144788.

Also fix an accidental implicit cast from the OptLevel enum
to an optional bool argument. MSVC warned on this, but gcc
didn't.

in the face of failures to import types, since blithely
passing on NULL types can sometimes lead to trouble.

Also eliminated a use of getAs and replaced it with
dyn_cast, which is more robust.

(sub)module, all of the names may be hidden, just the macro names may
be exposed (for example, after the preprocessor has seen the import of
the module but the parser has not), or all of the names may be
exposed. Importing a module makes its names, and the names in any of
its non-explicit submodules, visible to name lookup (transitively).

This commit only introduces the notion of name visible and marks
modules and submodules as visible when they are imported. The actual
name-hiding logic in the AST reader will follow (along with test cases).

Original commit message:
llvm-config: Replace with C++ version (was llvm-config-2).
 - Reapply of r144300, with lots of fixes/migration easement in between.
