Re-commit "llvm-isel-fuzzer: Handle a subset of backend flags in the exec name"
Here we add a secondary option parser to llvm-isel-fuzzer (and provide it for use with other fuzzers). With this, you can copy the fuzzer to a name like llvm-isel-fuzzer=aarch64-gisel for a fuzzer that fuzzer AArch64 with GlobalISel enabled, or fuzzer=x86_64 to fuzz x86, with no flags required. This should be useful for running these in OSS-Fuzz. Note that this handrolls a subset of cl::opts to recognize, rather than embedding a complete command parser for argv[0]. If we find we really need the flexibility of handling arbitrary options at some point we can rethink this. This re-applies 315545 using "=" instead of ":" as a separator for arguments. llvm-svn: 315557
