Record function attribute "stackrealign" instead of using backend option -force-align-stack. Also, make changes to the driver so that -mno-stack-realign is no longer an option exposed to the end-user that disallows stack realignment in the backend. Differential Revision: http://reviews.llvm.org/D11815 llvm-svn: 247451

clang/test/Driver/stackrealign.c REQUIRES clang-driver. GCC driver, for example cygwin, both "-mstackrealign" "-mno-stackrealign" are passed. llvm-svn: 247496

Stack realignment is a tristate. Add -mno-stackrealign to turn off all stack realignment, even with locals with alignment exceeding the ABI guarantee. llvm-svn: 145909
