Use shorter forms of CallInst ctors. Do not make `reopt_threshold' visible to the LLVM program, and do not pass it to the call to `reoptimizerInitialize'. Don't pass the GlobalVariable representing it to any of our helper methods. `reopt_threshold' is an internal parameter of the reoptimizer, which InstLoops does not need to know about. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7794 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | 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
