[clang][cli] Remove -f[no-]trapping-math from -cc1 command line This patch removes the -f[no-]trapping-math flags from the -cc1 command line. These flags are ignored in the command line parser and their semantics is fully handled by -ffp-exception-mode. This patch does not remove -f[no-]trapping-math from the driver command line. The driver flags are being used and do affect compilation. Reviewed By: dexonsmith, SjoerdMeijer Differential Revision: https://reviews.llvm.org/D93395

This adds new options -fdenormal-fp-math and passes through option -ffast-math to CC1, which are translated to function attributes and can e.g. be mapped on build attributes FP_exceptions and FP_denormal. Setting these build attributes allows better selection of floating point libraries. Differential Revision: https://reviews.llvm.org/D23840 llvm-svn: 280064

Use functions with prototypes when appropriate; NFC A significant number of our tests in C accidentally use functions without prototypes. This patch converts the function signatures to have a prototype for the situations where the test is not specific to K&R C declarations. e.g., void func(); becomes void func(void); This is the eleventh batch of tests being updated (there are a significant number of other tests left to be updated).
