SourceManager's getBuffer() and, therefore, could fail, along with
Preprocessor::getSpelling(). Use the Invalid parameters in the literal
parsers (string, floating point, integral, character) to make them
robust against errors that stem from, e.g., PCH files that are not
consistent with the underlying file system.
I still need to audit every use caller to all of these routines, to
determine which ones need specific handling of error conditions.

expanding directives withing macro expansions. This is undefined behavior
according to 6.10.3p11, so we might as well be undefined in ways similar to
GCC.

.def file for each library. This means that adding a diagnostic
to sema doesn't require all the other libraries to be rebuilt.

- Kill unnecessary #includes in .cpp files. This is an automatic
sweep so some things removed are actually used, but happen to be
included by a previous header. I tried to get rid of the obvious
examples and this was the easiest way to trim the #includes in one
fell swoop.
- We now return to regularly scheduled development.

related to pp-expressions. Doing so is pretty simple and this
patch implements it, yielding nice diagnostics like:
t.c:2:7: error: division by zero in preprocessor expression
#if 1 / (0 + 0)
~ ^ ~~~~~~~
t.c:5:14: error: expected ')' in preprocessor expression
#if (412 + 42
~~~~~~~~^
t.c:5:5: error: to match this '('
#if (412 + 42
^
t.c:10:10: warning: left side of operator converted from negative value to unsigned: -42 to 18446744073709551574
#if (-42 + 0U) / -2
~~~ ^ ~~
t.c:10:16: warning: right side of operator converted from negative value to unsigned: -2 to 18446744073709551614
#if (-42 + 0U) / -2
~~~~~~~~~~ ^ ~~

a) correct rejection of ',' in pp expressions.
b) the precedence of ',' was wrong w.r.t. ?:.
Thanks again to Neil for finding these and providing testcases.

lib dir and move all the libraries into it. This follows the main
llvm tree, and allows the libraries to be built in parallel. The
top level now enforces that all the libs are built before Driver,
but we don't care what order the libs are built in. This speeds
up parallel builds, particularly incremental ones.
