Akira Hatanaka bd9fc28444 [MCTargetAsmParser] Move the member varialbes that reference
MCSubtargetInfo in the subclasses into MCTargetAsmParser and define a
member function getSTI.

This is done in preparation for making changes to shrink the size of
MCRelaxableFragment. (see http://reviews.llvm.org/D14346).

Daniel Sanders 5762a4f9d1 [mips][ias] Range check uimm4 operands and fixed a bug this revealed.
Summary:
The bug was that the sldi instructions have immediate widths dependant on
their element size. So sldi.d has a 1-bit immediate and sldi.b has a 4-bit
immediate. All of these were using 4-bit immediates previously.

Daniel Sanders ea4f653d18 [mips][ias] Range check uimm2 operands and fix a bug this revealed.
Summary:
The bug was that the MIPS32R6/MIPS64R6/microMIPS32R6 versions of LSA and DLSA
(unlike the MSA version) failed to account for the off-by-one encoding of the
immediate. The range is actually 1..4 rather than 0..3.

Daniel Sanders d5a89418c5 [mips] Changed the way symbols are handled in dla and la instructions to allow simple expressions.
Summary:
An instruction like "(d)la $5, symbol+8" previously would have crashed the
assembler as it contains an expression. This is now fixed.
A few tests cases have also been changed to reflect these changes, however
these should only be syntax changes. Some new test cases have also been
added.

Summary:
Based on a patch by David Chisnall. I've modified the original patch as follows:
* Moved the expansion to the TargetStreamers so that the directive isn't
  expanded when emitting assembly.
* Fixed an operand order bug.
* Changed the move instructions from DADDu to OR to match recent changes to GAS.

Daniel Sanders e2982adc0b [mips] Add assembler support for the .cprestore directive.
Summary:
This assembler directive is used in O32 PIC to restore the current function's $gp after executing JAL's. The $gp is first stored on the stack at a user-specified offset.
It has the following format: ".cprestore 8" (where 8 is the offset).

This fixes llvm.org/PR20967.

Daniel Sanders 153010c52d Re-commit r247683: Replace Triple with a new TargetTuple in MCTargetDesc/* and related. NFC.
Summary:
This is the first patch in the series to migrate Triple's (which are ambiguous)
to TargetTuple's (which aren't).

For the moment, TargetTuple simply passes all requests to the Triple object it
holds. Once it has replaced Triple, it will start to implement the interface in
a more suitable way.

This change makes some changes to the public C++ API. In particular,
InitMCSubtargetInfo(), createMCRelocationInfo(), and createMCSymbolizer()
now take TargetTuples instead of Triples. The other public C++ API's have
been left as-is for the moment to reduce patch size.

This commit also contains a trivial patch to clang to account for the C++ API
change. Thanks go to Pavel Labath for fixing LLDB for me.

Daniel Sanders a699444094 [mips] Make the MipsAsmParser capable of knowing whether PIC mode is enabled or not.
Summary:
This information is needed to decide whether we do the PIC-only JAL expansions or not. It's also needed for an upcoming patch which implements the .cprestore assembler directive (which can only be used effectively in PIC mode).

By making this information available to the MipsAsmParser, we will know when to insert the instructions mandated by the .cprestore assembler directive and we will be able to give some useful warnings when we encounter a potential misuse of this directive.

Daniel Sanders 03f9c019d2 [mips] Fix li/la differences between IAS and GAS.
Summary:

- For la, unsigned 16-bit must use ori+addu rather than directly use ori.
- Correct tests on 32-bit immediates with 64-bit predicates by
  sign-extending the immediate beforehand. For example, isInt<16>(0xffff8000)
  should be true and use addiu.

Also split li/la testing into separate files due to their size.
