track "just a little more" location information for macro instantiations.
...
Now instead of just tracking the expansion history, also track the full
range of the macro that got replaced. For object-like macros, this doesn't
change anything. For _Pragma and function-like macros, this means we track
the locations of the ')'.
This is required for PR3579 because apparently GCC uses the line of the ')'
of a function-like macro as the location to expand __LINE__ to.

Fix rdar://6562329, a static analyzer crash Ted noticed on

wine sources. This was happening because HighlightMacros was
calling EnterMainFile multiple times on the same preprocessor
object and getting an assert due to the new #line stuff (the
file in question was bison output with #line directives).
The fix for this is to not reenter the file. Instead,
relex the tokens in raw mode, swizzle them a bit and repreprocess
the token stream. An added bonus of this is that rewrite macros
will now hilight the macro definition as well as its uses. Woo.
