that also includes the contents of the IdentifierInfo itself (the
various fields and flags, along with the chain of identifiers visible
at the top level that have that name).
We don't make any use of the hash table yet, except that our
identifier ID -> string mapping points into the hash table now.

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.

"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.

from a PCH file. It turns out that "Hello, World!" is bringing in 19%
of all of the statements in Carbon.h, so we need to be lazy.

This completes support for all of C (+ extensions). We can (again)
build a PCH file for Carbon.h.

Optimize PCH encoding for switch-case statements slightly, by making
the switch-case numbering local to a particular statement.

that does not require PCH support for statements. Only AddrLabelExpr,
StmtExpr, and BlockExpr remain (for C).

token length in the PCH file rather than trying (and failing) to
reconstruct it be getting the spelling token's length.

kind PCH handles that has an expression as an operand, so most of this
work is in the infrastructure to rebuild expression trees from the
serialized representation. We now store expressions in post-order
(e.g., Reverse Polish Notation), so that we can easily rebuild the
appropriate expression tree.

This allows it to accurately measure tokens, so that we get:
t.cpp:8:13: error: unknown type name 'X'
static foo::X P;
~~~~~^
instead of the woefully inferior:
t.cpp:8:13: error: unknown type name 'X'
static foo::X P;
~~~~ ^
Most of this is just plumbing to push the reference around.

non-inline external definitions (and tentative definitions) that are
found at the top level. The corresponding declarations are stored in a
record in the PCH file, so that they can be provided to the
ASTConsumer (via HandleTopLevelDecl) when the PCH file is read.

handle the definition of __builtin_va_list on x86-64, eliminate the
forced -triple in PCH tests to get better coverage.
