[Driver] Fix handling of -fbuiltin/-fcommon when combined with -mkernel -mkernel enables -fno-builtin and -fno-common by default, but allows -fbuiltin and -fcommon to override that. However "-fbuiltin -fno-builtin" is treated the same as "-fbuiltin" which is wrong, so fix that. Also fixes similar behaviour when -fno-common is default.

Recommit #2 "[Driver] Default to -fno-common for all targets" After a first attempt to fix the test-suite failures, my first recommit caused the same failures again. I had updated CMakeList.txt files of tests that needed -fcommon, but it turns out that there are also Makefiles which are used by some bots, so I've updated these Makefiles now too.

[ARM] Pass subtarget feature "+long-calls" instead of passing backend option "-arm-long-calls". This change allows using -mlong-calls/-mno-long-calls for LTO and enabling or disabling long call on a per-function basis. rdar://problem/21529937 Differential Revision: http://reviews.llvm.org/D9414 llvm-svn: 241565

// CHECK-ARM: "-target-feature" "+long-calls"
[ARM] Pass subtarget feature "+strict-align". This commit changes the driver to save subtarget feature "+strict-align" to the IR instead of using backend option "arm-strict-align". This is needed for LTO. Also, move the logic in ARM backend that was deciding whether strict alignment should be forced to the front-end. rdar://problem/21529937 http://reviews.llvm.org/D11472 llvm-svn: 243489
