John McCall 5996699834 Revise r110163: don't mark weak functions nounwind, because the optimizer 
treats that as a contract to be fulfilled by any replacements.

John McCall 8601a75118 Do a very simple pass over every function we emit to infer whether we can 
mark it nounwind based on whether it contains any non-nounwind calls.

Daniel Dunbar 8fbe78f6fc 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).

Daniel Dunbar 8b57697954 Eliminate &&s in tests. 
- 'for i in $(find . -type f); do sed -e 's#\(RUN:.*[^ ]\) *&& *$#\1#g' $i | FileUpdate $i; done', for the curious.

Daniel Dunbar a45cf5b6b0 Rename clang to clang-cc. 
Tests and drivers updated, still need to shuffle dirs.
