The fuzzer argument parser will ignore all options starting with '--' so
operation mode options should begin with '--' and fuzzer options should begin
with '-'. Fuzzer arguments must still follow --fuzzer-args so that they escape
the parsing performed by the CommandLine library.

Summary:
For fixed length instructions, we can use -max_len to limit the fuzzer to a
single instruction. This doesn't work for variable length instruction sets
since a 4-byte input could consist of one 4-byte instruction or two 2-byte
instructions.
This patch adds a --insn-limit to llvm-mc-fuzzer to limit the input in
terms of instructions processed.

Summary:
Only the disassembler is supported in this patch but it has already found a few
issues in the Mips disassembler (mostly invalid instructions being successfully
disassembled).
