Centralize the logic for handling -m* options and fix pr16943. This moves the logic for handling -mfoo -mno-foo from the driver to -cc1. It also changes -cc1 to apply the options in order, fixing pr16943. The handling of -mno-mmx -msse is now an explicit special case. llvm-svn: 188817

// RUN: %clang -target i386-unknown-unknown -### -S %s -msse -msse4 -mno-sse -mno-mmx -msse 2>&1 | FileCheck %s
Make the msse4/mno-sse4 flags aliases of the maximum sse values they enable/disable. This fixes two things: a) sse4 isn't actually a target feature, don't treat it as one. b) we weren't correctly disabling sse4.1 when we'd pass -mno-sse4 after enabling it, thus passing preprocessor directives and (soon) passing the function attribute as well when we shouldn't. llvm-svn: 233223

// CHECK: "pentium4" "-target-feature" "+sse4.2" "-target-feature" "-mmx" "-target-feature" "+sse"
Move the logic for selecting the last feature in the command line to the driver. This is a partial revert of r188817 now that the driver handles -target-feature in a single place. llvm-svn: 188910

// Note that we filter out all but the last -m(no)sse.
Ignore -mieee-fp. It looks like clang always produce code with the ieee comparisons, so it is safe to ignore this flag (we still error on -mno-ieee-fp). llvm-svn: 191912

// Test that we don't produce an error with -mieee-fp.
Fix test. With -### clang return 0, so we have to use FileCheck to see if there was an error. llvm-svn: 191923

// RUN: %clang -### %s -mieee-fp -S 2>&1 | FileCheck --check-prefix=IEEE %s
// IEEE-NOT: error: unknown argument
