allocating them from a recycling bump pointer allocator.  This 
reduces malloc/free traffic of parse-noop (but no other mode),
which makes sharking -parse-noop more meaningful.

rearrange GetIdentifierInfo so that the fast path can be partially inlined into PTHLexer::Lex.  This speeds up the user time of PTH -Eonly by another 2ms (4.4%)

each #ifdef.

unsigned char before assembling a larger integer.

TextDiagnosticPrinter where it should have been using the canonical

method.  This lets us clean up the interface and make it more obvious that
this method is *really really* _Pragma specific.

Note that _Pragma handling uglifies the Lexer in the critical path.  It would
be very interesting to consider making _Pragma remapping be a new special
lexer class of its own.
