Improve llvm-mc disassembler mode and refactor ARM tests to use it

This allows "llvm-mc -disassemble" to accept two new features:
+ Using comma as a byte separator
+ Grouping bytes with '[' and ']' pairs.

The behaviour outside a [...] group is unchanged. But within the group once
llvm-mc encounters a true error, it stops rather than trying to resynchronise
the stream at the next byte. This is more useful for disassembly tests, where
we have an almost-instruction in mind and don't care what the misaligned
interpretation would be. Particularly if it means llvm-mc won't actually see
the next intended almost-instruction.

As a side effect, this means llvm-mc can disassemble its own -show-encoding
output if copy-pasted.

Add -disassemble support for -show-inst and -show-encode capability llvm-mc. Also refactor so all MC paraphernalia are created once for all uses as much as possible.

The test change is to account for the fact that the default disassembler behaviour has changed with regards to specifying the assembly syntax to use.

Clients are responsible for initializing the targets, remove it from the disassembler API.

This will break users of the LLVMCreateDisasm API (not that I know of any). They have to call the
LLVMInitializeAll* functions from llvm-c/Target.h themselves now. edis' C API in all its horribleness
should be unaffected.
