Chris Lattner 5a5d67101b Eagerly resolve the spelling location of the tokens in a definition ... of a macro. Since these tokens may themselves be from macro expansions, we need to resolve down to the spelling loc when the macro ends up being instantiated. Instead of resolving this for each token expanded from the macro definition, just do it once when the macro is defined. This speeds up clang on c99-intconst-1.c from 2.66s to 2.43s (9.5%), reducing the FileID lookups from 407244 linear and 114175649 binary to 2529040 linear and 64771121 binary. llvm-svn: 62993		2009-01-26 04:06:48 +00:00
