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.

FunctionDecl::getBody() is getting an ASTContext argument for use in
...
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.

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.

tweak redefinition of a typedef a bit to fix a couple of problems:
...
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.

Fix two embarrassing PCH bugs:
...
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.

implement a new clang-cc option -dump-build-information=filename which causes the
...
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.
