Switch the fixed-length disassembler to be table-driven.
Refactor the TableGen'erated fixed length disassemblmer to use a
table-driven state machine rather than a massive set of nested
switch() statements.
As a result, the ARM Disassembler (ARMDisassembler.cpp) builds much more
quickly and generates a smaller end result. For a Release+Asserts build on
a 16GB 3.4GHz i7 iMac w/ SSD:
Time to compile at -O2 (averaged w/ hot caches):
Previous: 35.5s
New: 8.9s
TEXT size:
Previous: 447,251
New: 297,661
Builds in 25% of the time previously required and generates code 66% of
the size.
Execution time of the disassembler is only slightly slower (7% disassembling
10 million ARM instructions, 19.6s vs 21.0s). The new implementation has
not yet been tuned, however, so the performance should almost certainly
be recoverable should it become a concern.

TargetRegisterClasses defined in MipsGenRegisterInfo.inc.

In MipsDisassembler.cpp, instead of defining register class tables, use the ones
that are generated by TableGen and are already available in
MipsGenRegisterInfo.inc. Suggested by Jakob Stoklund Olesen.
Also, fix bug in function DecodeAFGR64RegisterClass.
