Jack Carter 3eb663b037 [mips][msa] Direct Object Emission for 3R instructions.
This is the first set of instructions with a ".b" modifier thus we need to add the required code to disassemble a MSA128B register class.

Jack Carter 5dc8ac92b9 [mips][msa] Direct Object Emission support for the MSA instruction set.
In more detail, this patch adds the ability to parse, encode and decode MSA registers ($w0-$w31). The format of 2RF instructions (MipsMSAInstrFormat.td) was updated so that we could attach a test case to this patch i.e., the test case parses, encodes and decodes 2 MSA instructions. Following patches will add the remainder of the instructions.

Note that DecodeMSA128BRegisterClass is missing from MipsDisassembler.td because it's not yet required at this stage and having it would cause a compiler warning (unused function).

Akira Hatanaka 14e31a2fe7 [mips] Define register class FGRH32 for the high half of the 64-bit floating

definitions for instructions mfhc1 and mthc1. Also, remove sub-register indices
sub_fpeven and sub_fpodd and use sub_lo and sub_hi instead.

Benjamin Kramer 534d3a4670 Remove the Copied parameter from MemoryObject::readBytes.
There was exactly one caller using this API right, the others were relying on
specific behavior of the default implementation. Since it's too hard to use it
right just remove it and standardize on the default behavior.

Defines away PR16132.

Reed Kotler ec8a54904e Remove the form field from Mips16 instruction formats and set things
up so that we can apply the direct object emitter patch. This patch
should be a nop right now and it's test is to not break what is already
there.

Jack Carter 7ab15fafe3 This is a resubmittal. For some reason it broke the bots yesterday
but I cannot reproduce the problem and have scrubed my sources and
even tested with llvm-lit -v --vg.
Formatting fixes. Mostly long lines and 
blank spaces at end of lines.

Chandler Carruth ed0881b2a6 Use the new script to sort the includes of every file under lib.
Sooooo many of these had incorrect or strange main module includes.
I have manually inspected all of these, and fixed the main module
include to be the nearest plausible thing I could find. If you own or
care about any of these source files, I encourage you to take some time
and check that these edits were sensible. I can't have broken anything
(I strictly added headers, and reordered them, never removed), but they
may not be the headers you'd really like to identify as containing the
API being implemented.

Many forward declarations and missing includes were added to a header
files to allow them to parse cleanly when included first. The main
module rule does in fact have its merits. =]

Akira Hatanaka ecabd1a5d2 MIPS DSP: add functions which decode DSP and accumulator registers.

Jim Grosbach ecaef49f59 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.

Akira Hatanaka da448fe0b1 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.
