Akira Hatanaka 2c544d8ed5 [mips] Make "b" (unconditional branch) a pseudo. "b" is an assembly idiom, which is
equivalent to "beq $zero, $zero, offset".

Akira Hatanaka 2ffc5734e7 [mips] Expand pseudo multiply/divide instructions in MipsCodeEmitter.cpp.
This patch fixes the following two tests which have been failing on
llvm-mips-linux builder since r178403:

LLVM :: Analysis/Profiling/load-branch-weights-ifs.ll
LLVM :: Analysis/Profiling/load-branch-weights-loops.ll

Akira Hatanaka bf1af1acc7 [mips] Expand pseudo instructions before they are emitted in
MipsCodeEmitter.cpp.

JALR and NOP are expanded by function emitPseudoExpansionLowering, which is not
called when the old JIT is used.

llvm-mips-linux builder:

Chandler Carruth 9fb823bbd4 Move all of the header files which are involved in modelling the LLVM IR
into their new header subdirectory: include/llvm/IR. This matches the
directory structure of lib, and begins to correct a long standing point
of file layout clutter in LLVM.

There are still more header files to move here, but I wanted to handle
them in separate commits to make tracking what files make sense at each
layer easier.

The only really questionable files here are the target intrinsic
tablegen files. But that's a battle I'd rather not fight today.

I've updated both CMake and Makefile build systems (I think, and my
tests think, but I may have missed something).

I've also re-sorted the includes throughout the project. I'll be
committing updates to Clang, DragonEgg, and Polly momentarily.

Akira Hatanaka 4c128509a5 Classic JIT is still being supported by MIPS, along with MCJIT.
This change adds endian-awareness to MipsJITInfo and emitWordLE in
MipsCodeEmitter has become emitWord now to support both endianness.

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 3e7ba76157 Remove aligned/unaligned load/store fragments defined in MipsInstrInfo.td and
use load/store fragments defined in TargetSelectionDAG.td in place of them.
Unaligned loads/stores are either expanded or lowered to target-specific nodes,
so instruction selection should see only aligned load/store nodes.

No changes in functionality.

Bruno Cardoso Lopes d5b2834fb7 Improve Mips JIT.
Implement encoder methods getJumpTargetOpValue and getBranchTargetOpValue
for jmptarget and brtarget Mips tablegen operand types in the code emitter
for old-style JIT. Rename the pc relative relocation for branches - new
name is Mips::reloc_mips_pc16.

Evan Cheng 7f8e563a69 Add bundle aware API for querying instruction properties and switch the code
generator to it. For non-bundle instructions, these behave exactly the same
as the MC layer API.

For properties like mayLoad / mayStore, look into the bundle and if any of the
bundled instructions has the property it would return true.
For properties like isPredicable, only return true if *all* of the bundled
instructions have the property.
For properties like canFoldAsLoad, isCompare, conservatively return false for
bundles.

Evan Cheng 2a81dd4a3c First chunk of MachineInstr bundle support.
1. Added opcode BUNDLE
2. Taught MachineInstr class to deal with bundled MIs
3. Changed MachineBasicBlock iterator to skip over bundled MIs; added an iterator to walk all the MIs
4. Taught MachineBasicBlock methods about bundled MIs

Bruno Cardoso Lopes c85e3ff334 Mips MC object code emission improvements:
"With this patch we can now generate runnable Mips code through LLVM
direct object emission. We have run numerous simple programs, both C
and C++ and with -O0 and -O3 from the output. The code is not production
ready, but quite useful for experimentation." Patch and message by
Jack Carter

Bruno Cardoso Lopes 71133fe9c6 This patch handles unaligned loads and stores in Mips JIT. Mips backend
implements unaligned loads and stores with assembler macro-instructions
ulw, usw, ulh, ulhu, ush, and this patch emits corresponding instructions
instead of these macros. Since each unaligned load/store is expanded
into two corresponding loads/stores where offset for second load/store is
modified by +3 (for words) or +1 (for halfwords).

Bruno Cardoso Lopes 2312a3aaa0 Final patch that completes old JIT support for Mips:
-Fix binary codes and rename operands in .td files so that automatically
generated function MipsCodeEmitter::getBinaryCodeForInstr gives correct
encoding for instructions.
-Define new class FMem for instructions that access memory.
-Define new class FFRGPR for instructions that move data between GPR and
FPU general and control registers.
-Define custom encoder methods for memory operands, and also for size
operands of ext and ins instructions.
-Only static relocation model is currently implemented.

Bruno Cardoso Lopes 483c269a33 One more patch towards JIT support for Mips.
- Add TSFlags for the instruction formats. The idea here is to use
  as much encoding as possible from getBinaryCodeForInstr, and having
  TSFLags formats for that would make it easier to encode most part
  of the instructions (since Mips encodings are pretty straightforward)
- Improve the mips mechanism for compilation callback
- Add Mips specific code for invalidating the instruction cache
- Next patch will address wrong tablegen encoding

Commit msg added by my own but the patch is from Sasa Stankovic.

Bruno Cardoso Lopes d1d9c78650 Added the infrastructute necessary for MIPS JIT support. Patch by Vladimir
Stefanovic. I removed the part that actually emits the instructions cause
I want that to get in better shape first and in incremental steps. This
also makes it easier to review the upcoming parts.
