Douglas Gregor 8324327993 For source location entries that describe instantiations, encode the
token length in the PCH file rather than trying (and failing) to
reconstruct it be getting the spelling token's length.

Douglas Gregor 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.

Douglas Gregor feb84b0074 PCH support for a few very, very simple kinds of expressions. Hook up

enum constant initializers, and bitfield widths.

Douglas Gregor 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.

Douglas Gregor a541485bab Partial PCH support for FileScopeAsmDecl and BlockDecl. Both require
expression or statement serialization before we can test them.

Douglas Gregor 183671e2d2 PCH support for record decls/types and their fields. Now that we can
handle the definition of __builtin_va_list on x86-64, eliminate the
forced -triple in PCH tests to get better coverage.

Chris Lattner c523d8e88c now that we have an identifier table in the PCH file, finish hooking up
macro deserialization.  We now correctly install II's in tokens, handle
function-like macros, etc.

Douglas Gregor 3ed42cb0b3 Store unique IDs for identifiers in the PCH file. Use some bitmangling
so that we only need to perform the lookup and identifier resolution
once per identifier in the PCH file.

Douglas Gregor 92863e475e Compare the predefines buffer in the PCH file with the predefines
buffer generated for the current translation unit. If they are
different, complain and then ignore the PCH file. This effectively
checks for all compilation options that somehow would affect
preprocessor state (-D, -U, -include, the dreaded -imacros, etc.).

When we do accept the PCH file, throw away the contents of the
predefines buffer rather than parsing them, since all of the results
of that parsing are already stored in the PCH file. This eliminates
the ugliness with the redefinition of __builtin_va_list, among other
things.

Chris Lattner 34321bcd0b add support for reading macros. This does all the reading (with a bunch of
fixme's, e.g. for tokens with identifiers) but does not actually install
them.  Some details with the predefines buffer needs to be sorted out first.

Douglas Gregor 55abb2389d Implement serialization/deserialization of LangOptions in the PCH
file. When de-serializing LangOptions, we check that the
currently-provided language options are consistent with the options
used to compile the PCH file. If they are not, we emit a diagnostic
and ignore the PCH file.

Chris Lattner baa52f47c1 emit function-like and object-like macros to the PCH file.
Note that we don't do anything useful with identifier infos yet
and don't emit the tokens that the macros are defined to.

functionality change.

Douglas Gregor a7f71a91c5 PCH serialization/deserialization of the source manager. With this
improvement, source locations read from the PCH file will properly
resolve to the source files that were used to build the PCH file
itself.

Once we have the preprocessor state stored in the PCH file, source
locations that refer to macro instantiations that occur in the PCH
file should have the appropriate instantiation information.

Douglas Gregor ef84c4b434 Implementation of pre-compiled headers (PCH) based on lazy
de-serialization of abstract syntax trees.

PCH support serializes the contents of the abstract syntax tree (AST)
to a bitstream. When the PCH file is read, declarations are serialized
as-needed. For example, a declaration of a variable "x" will be
deserialized only when its VarDecl can be found by a client, e.g.,
based on name lookup for "x" or traversing the entire contents of the
owner of "x".

This commit provides the framework for serialization and (lazy)
deserialization, along with support for variable and typedef
declarations (along with several kinds of types). More
declarations/types, along with important auxiliary structures (source
manager, preprocessor, etc.), will follow.
