04f2d14d6a Add pch reader/writer support for ObjCMethodDecl. 
Test will be enabled with ObjCInterfaceDecl is added.

652d82a096 Store the type ID for __builtin_va_list in the PCH file, so that the 
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.

3c3aa61758 Lazy deserialization of function bodies for PCH files. For the Carbon 
"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.

08f0129003 Keep track of the number of statements/expressions written to and read 
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.

f994f062fd PCH support for inline assembly statements. 
This completes support for all of C (+ extensions). We can (again)
build a PCH file for Carbon.h.

the switch-case numbering local to a particular statement.

4c5cd33527 PCH support for CompoundLiteralExpr. This is the last C expression

f0b575f79d Add PCH support for ImplicitCastExprs. This is the first expression 
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.

184e65d363 Change Lexer::MeasureTokenLength to take a LangOptions reference. 
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.

1a0d0b9acc When writing a PCH file, keep track of all of the non-static, 
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.

183671e2d2 PCH support for record decls/types and their fields. Now that we can

a8854654ac Make the reading of the line table from a PCH file more robust against 
the unlikely event that the filename IDs in the stored line table end
up being different from the filename IDs in the newly-created line
table.
