Add -femulated-tls flag to select the emulated TLS model. This will be used for old targets like Android that do not support ELF TLS models. Differential Revision: http://reviews.llvm.org/D10524 llvm-svn: 243441

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.
