AST context's __builtin_va_list type will be set when the PCH file is
loaded. This fixes the crash when CodeGen'ing a va_arg expression
pulled in from a PCH file.

Highlights: PP::isNextPPTokenLParen() no longer eats the (
when present. We now simplify slightly the logic parsing
macro arguments. We now handle PR3937 and other related cases
correctly.

"Hello, World!", this takes us from deserializing 6469
statements/expressions down to deserializing 1
statement/expression. It only translated into a 1% improvement on the
Carbon-prefixed 403.gcc, but (a) it's the right thing to do, and (b)
we expect this to matter more once we lazily deserialize identifiers.

lazy PCH deserialization. Propagate that argument wherever it needs to
be. No functionality change, except that I've tightened up a few PCH
tests in preparation.

1. We had logic in sema to decide whether or not to emit the error
based on manually checking whether in a system header file.
2. we were allowing redefinitions of typedefs in class scope in C++
if in header file.
3. there was no way to force typedef redefinitions to be accepted
by the C compiler, which annoys me when stripping linemarkers out
of .i files.
The fix is to split the C++ class typedef redefinition path from the
C path, and change the C path to be a warning that normally maps to
error. This causes it to properly be ignored in system headers,
etc. and gives us a way to control it. Passing
-Wtypedef-redefinition now turns the error into a warning.
One behavior change is that we now diagnose cases where you redefine
a typedef in your .c file that was defined in a header file. This
seems like reasonable behavior, and the diagnostic now indicates that
it can be controlled with -Wtypedef-redefinition.

1) Accidentally used delete [] on an array of statements that was allocated with ASTContext's allocator
2) Deserialization of names with multiple declarations (e.g., a struct and a function) used the wrong mangling constant, causing it to view declaration IDs as Decl*s.
403.gcc builds and links properly.

compiler to dump random stuff from the build into the file. Right now this
amounts to dumping command line arguments and diagnostics to the file.
The idea is that you can set an envvar, do a world build of an OS, then grep
through all the logs for interesting things or something.
Daniel, please wire the driver up to do something with this.
