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.

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.

risk!) of weird null DiagnosticBuilder's floating around.
