Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'. - This is designed to make it obvious that %clang_cc1 is a "test variable" which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it can be useful to redefine what gets run as 'clang -cc1' (for example, to set a default target). llvm-svn: 91446

/* RUN: %clang_cc1 -E %s | grep 'a 3'
* RUN: %clang_cc1 -E %s | grep 'b 16'
* RUN: %clang_cc1 -E -P %s | grep 'a 3'
* RUN: %clang_cc1 -E -P %s | grep 'b 16'
* RUN: %clang_cc1 -E %s | not grep '# 0 '
fix PR7360: -P mode turns off line markers, but not blank space. Apparently some programs which abuse the preprocessor depend on this. llvm-svn: 105889

The flags on tokens indicate whether they are the start of a *physical* line, not the start of a logical line. Be careful about this distinction, which affects when newlines are printed and when paste-avoidance happens, etc. This fixes PR1848, thanks to Neil for noticing this! llvm-svn: 44743
