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 2013-08-21 02:57:55 +08:00			`// RUN: %clang -target i386-unknown-unknown -### -S %s -msse -msse4 -mno-sse -mno-mmx -msse 2>&1 \| FileCheck %s`
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 2013-08-22 01:34:32 +08:00			`// CHECK: "pentium4" "-target-feature" "+sse4" "-target-feature" "-mmx" "-target-feature" "+sse"`
