clang executable (when built with gcc 4.2 on the mac) from 14519740 to 
14495028 bytes.  This shrinks individual object files as well: SemaChecking
from 23580->22248, SemaDeclObjc from 61368->57376, SemaExpr from 
115628->110516, as well as several others.

would not eat the "-1" in "0x0p-1", but LiteralSupport would accept
it when extensions are on.  This caused strangeness and failures 
when hexfloats were properly treated as an extension (not error)
in LiteralSupport.

"It simplifies the type legalization part a bit, and produces better code by
teaching SelectionDAG about the extra bits in an i8 SADDO/UADDO node.  In
essence, I spontaneously decided that on x86 this i8 boolean result would be
either 0 or 1, and on other platforms 0/1 or 0/-1, depending on whether the
platform likes it's boolean zero extended or sign extended."

its call sites.  This makes it more explicit when the hasError flag is
getting set and removes a confusing difference in behavior between
PP.Diag and Diag in this code.

(and carefully calculated) effect of allowing the compiler to reason
about the aliasing properties of DiagnosticBuilder object better,
allowing the whole thing to be promoted to registers instead of
resulting in a ton of stack traffic.

While I'm not very concerned about the performance of the Diag() method
invocations, I *am* more concerned about their code size and impact on the
non-diagnostic code.  This patch shrinks the clang executable (in 
release-asserts mode with gcc-4.2) from 14523980 to 14519816 bytes.  This
isn't much, but it shrinks the lexer from 38192 to 37776, PPDirectives.o
from 31116 to 28868 bytes, etc.

and one for pulling structured information out of the diagnostic when
formatting and presenting it.

There is no functionality change with this patch.

In PTHLexer::DiscardToEndOfLine() use Lex() instead of AdvanceToken().  This handles transitions in the preprocessor state.

When creating the raw tokens for PTHLexer, make sure the token representing the file to include is checked for being an identifier.
