only sometimes not significant, so this quick check in the parser will
need refactored into something more robust soon-ish. This gets some
basics working in the meantime.

instead.

ARM .code directive should always go to the streamer.
...
Even if there's no mode switch performed, the .code directive should still
be sent to the output streamer. Otherwise, for example, an output asm stream
is not equivalent to the input stream which generated it (a dependency on
the input target triple arm vs. thumb is introduced which was not originally
there).

invalid-LDR_PRE-arm.txt was already passing, but for the wrong reasons. We were failing to specify enough fixed bits of LDR_PRE/LDRB_PRE, resulting in decoding conflicts. Separate them into immediate vs. register versions, allowing us to specify the necessary fixed bits. This in turn results in the test being decoded properly, and being rejected as UNPREDICTABLE rather than a hard failure.
