Daniel Dunbar be947083d2 Speed up NumericLiteralParser::GetIntegerValue.
- Implement fast path when value easily fits in a uint64.
 - ~6x faster, translates to 1-2% on Cocoa.h

Chris Lattner fb8b8f298c Fix the root cause of PR2750 instead of the side effect.
NumericLiteral parser is not careful about overrun because
it should never be possible.  It implicitly expects that its
input matched the regex for pp-constant.  Because of this, it
knows it can't be pointing to a prefix of something that
looks like a number.  This is all fine, except that __LINE__
does not prevent implicit concatenation from happening.  Fix
__LINE__ to not do this.

Eli Friedman ee29c9c2fc Fix for PR2750; don't check for an 'e' in the trash after the token.
Note that this isn't really a complete fix; I think there are other 
potential overrun situations.  I don't really know what the best 
systematic fix is, though.

Daniel Dunbar 56fdb6ae69 More #include cleaning
- 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.

Chris Lattner c94ad4abcb In c89 mode accept hex fp constants as an extension:
t2.c:1:17: warning: hexadecimal floating constants are a C99 feature
long double d = 0x0.0000003ffffffff00000p-16357L;
                ^

instead of emitting a weird error message that doesn't make sense:

t2.c:1:41: error: hexadecimal floating constants require an exponent
long double d = 0x0.0000003ffffffff00000p-16357L;
                                        ^

Chris Lattner 48a9b9beeb when emitting diagnostics about some character in a numeric
literal, indicate what character the error is about or where
it would be.  For example:

pr2241.c:1:17: error: exponent has no digits
float f[] = { 1e  , 1ee0 };
                ^

Chris Lattner 7a51313d8a Make a major restructuring of the clang tree: introduce a top-level
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.
