The right way to parse arch names is by creating a triple. This was
using getArchTypeForLLVMName before, which doesn't really do the right
thing here.

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.

FuzzMutate might not be the best place for these, but it makes more
sense than an entirely new library for now. This will make setting up
fuzz targets with consistent CLI handling easier.
