b001cb6423 [mips] Add hardware register name "hwr_ulr" ($29)
The canonical name when printing assembly is still $29. The reason is that
GAS does not accept "$hwr_ulr" at the moment.

This addresses the comments from r221307, which reverted the original
commit r221299.

d3da72c5b3 Recommit "[mips] Add names and tests for the hardware registers"
The original commit r221299 was reverted in r221307.  I removed the name
"hrw_ulr" ($29) from the original commit because two tests were failing.

1dd631fe02 llvm-objdump: Skip empty sections when dumping contents
Empty sections are just noise when using objdump.
This is similar to what binutils does.

ea60f51d87 [mips] Improve error/warning messages and testing for the .cpload assembler directive.
Summary:
Improved warning message when using .cpload inside a reorder section and added an error message for using .cpload with Mips16 enabled.
Modified the tests to fit with the changes mentioned above, added a test-case for the N32 ABI in cpload.s and did some reformatting to make the tests easier to read.

dd3894aa8f [mips] Improve support for the .set mips16/nomips16 assembler directives.
Summary:
Appropriately set/clear the FeatureBit for Mips16 when these assembler directives are used and also emit ".set nomips16" (previously, only ".set mips16" was being emitted).

These improvements allow for better testing of the .cpload/.cprestore assembler directives (which are not supposed to work when Mips16 is enabled).

Test Plan: The test is bare-bones because there are no MC tests for Mips16 instructions (there's only one, which checks that the Mips16 ELF header flag gets set), and that suggests to me that it has not been implemented yet in the IAS.

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.

Daniel Sanders
98b419bff7 [mips] Add assembler support for '.set mipsX'.
Summary:
This patch also fixes an issue with the way the Mips assembler enables/disables architecture
features. Before this patch, the assembler never disabled feature bits. For example,
.set mips64
.set mips32r2

would result in the 'OR' of mips64 with mips32r2 feature bits which isn't right.
Unfortunately this isn't trivial to fix because there's not an easy way to clear
feature bits as the algorithm in MCSubtargetInfo (ToggleFeature) only clears the bits
that imply the feature being cleared and not the implied bits by the feature (there's a
better explanation to the code I added).
