Summary:
Expand list of supported targets for Mips to include mips32 r1.
Previously it only include r2. More patches are coming where there is
a difference but in the current patches as pushed upstream, r1 and r2
are equivalent.
Test Plan:
simplestorefp1.ll
add new build bots at mips to test this flavor at both -O0 and -O2

This commit adds aliases for the sync instruction (synciobdma,
syncs, syncw, syncws) which are used by the Octeon CPU.

Summary:
This directive is used to reset the assembler options to their initial values.
Assembly programmers use it in conjunction with the ".set mipsX" directives.
This patch depends on the .set push/pop directive (http://reviews.llvm.org/D4821).

Summary:
The GPR size is more a property of the subtarget than that of the ABI so move
this information to the MipsSubtarget.
No functional change.

Summary: Found a couple of cases where unsigned was still being used. These two should be the last ones in the (entire) Mips backend.

This is the final round of renaming. This changes tblgen to emit lower-case
function names for FastEmitInst_* and FastEmit_*, and updates all its uses
in the source code.

Summary:
This directive is similar to ".set mipsX".
It is used to change the CPU target of the assembler, enabling it to accept instructions for a specific CPU.
This patch only implements the r4000 CPU (which is treated internally as generic mips3) and the generic ISAs.

ARM in particular is getting dangerously close to exceeding 32 bits worth of
possible subtarget features. When this happens, various parts of MC start to
fail inexplicably as masks get truncated to "unsigned".
Mostly just refactoring at present, and there's probably no way to test.

It causes a number of regressions when -fintegrated-as is enabled. This happens
because there are codegen-only instructions that incorrectly uses the first
operand as the encoding for the $fcc register. The regressions do not occur when
-via-file-asm is also given.

I've made some minor changes to the original, such as improving the formatting and adding some comments, and I've also added a test case.

Add header guards to files that were missing guards. Remove #endif comments
as they don't seem common in LLVM (we can easily add them back if we decide
they're useful)

Summary:
Moved some calls to setCanHaveModuleDir to the MipsTargetStreamer base class and removed the resulting empty functions from the MipsTargetELFStreamer class.
Also fixed a missing call to setCanHaveModuleDir in MipsTargetELFStreamer::emitDirectiveSetMicroMips.

Patch by Matheus Almeida and Toma Tabacu
The lld test failure on the previous attempt to commit was caused by the
addition of the .pdr section causing the offsets it was checking to change.
This has been fixed by removing the .ent/.end directives from that test since
they weren't really needed.

Also added the testcase that should have been in r215194.
This behaviour has surprised me a few times now. The problem is that the
generated MipsSubtarget::ParseSubtargetFeatures() contains code like this:
if ((Bits & Mips::FeatureABICalls) != 0) IsABICalls = true;
so '-abicalls' means 'leave it at the default' and '+abicalls' means 'set it to
true'. In this case, (and the similar -modd-spreg case) I'd like the code to be
IsABICalls = (Bits & Mips::FeatureABICalls) != 0;
or possibly:
if ((Bits & Mips::FeatureABICalls) != 0)
IsABICalls = true;
else
IsABICalls = false;
and preferably arrange for 'Bits & Mips::FeatureABICalls' to be true by default
(on some triples).
