Migrate libcalls-fno-builtin.c test from checking optimized assembly
to checking for attributes on the call site - and fix up builtin functions that we were testing for but not ensuring wouldn't be optimized by the backend. Leave one set of asm tests to make sure that we're also communicating builtin-ness to TLI. llvm-svn: 333154
