Merged in changes between PRE11_ROOT and LLVM_PRE111 (i.e. the beginning of
the pre-release 1.1 branch and pre-release 1.1.1). Made the USE_SPEC option work. Silenced unnecessary error output from the cmp command when checking for updates to lex/yacc generated files. This fixes a problem where we get error messages the first time the file is generated. Fixed the distclean option. It is now in the Makefile (i.e. only runs in the top level source directory), removes more files, and plays nicely with external project Makefiles. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7780 91177308-0d34-0410-b5e6-96231b3b80d8
