These actions are extremely widely used (identifier expressions and literals); still no performance regression.

doing very similar pointer capture analysis.
Factor out the common logic.  The new version
is from FunctionAttrs since it does a better
job than the version in BasicAliasAnalysis

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.

putc, puts, perror, vscanf and vsscanf from getting annotations.

Add annotations for eight printf functions, memalign, pread and pwrite.

On Linux, llvm-gcc sometimes renames strdup, getc, putc, strtok_r, scanf and
sscanf. Match the alternate function names.

Fix a crash annotating opendir.

Don't mark fsetpos's second parameter as nocapture. It's supposed to be
captured.

Do mark fopen's path and mode strings as nocapture. Mark ferror as readonly,
but not fileno which may set errno.

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%)

unsigned char before assembling a larger integer.
