8782707f50 Implement a DAGCombine in MipsISelLowering.cpp which transforms the following 
pattern:

(add v0, (add v1, abs_lo(tjt))) => (add (add v0, v1), abs_lo(tjt))

"tjt" is a TargetJumpTable node.

4147e4d054 Make the following changes in MipsAsmPrinter.cpp: 
- Remove code which lowers pseudo SETGP01.
- Fix LowerSETGP01. The first two of the three instructions that are emitted to
  initialize the global pointer register now use register $2.
- Stop emitting .cpload directive.

27ba61df9f Insert instructions to the entry basic block which initializes the global 
pointer register. 


This is the first of the series of patches which clean up the way global pointer
register is used. The patches will make the following improvements:

- Make $gp an allocatable temporary register rather than reserving it.
- Use a virtual register as the global pointer register and let the register
  allocator decide which register to assign to it or whether spill/reloads are
  needed.
- Make sure $gp is valid at the entry of a called function, which is necessary
  for functions using lazy binding.
- Remove the need for emitting .cprestore and .cpload directives.

9e67db4af1 Flip the new block-placement pass to be on by default. 
This is mostly to test the waters. I'd like to get results from FNT
build bots and other bots running on non-x86 platforms.

This feature has been pretty heavily tested over the last few months by
me, and it fixes several of the execution time regressions caused by the
inlining work by preventing inlining decisions from radically impacting
block layout.

I've seen very large improvements in yacr2 and ackermann benchmarks,
along with the expected noise across all of the benchmark suite whenever
code layout changes. I've analyzed all of the regressions and fixed
them, or found them to be impossible to fix. See my email to llvmdev for
more details.

I'd like for this to be in 3.1 as it complements the inliner changes,
but if any failures are showing up or anyone has concerns, it is just
a flag flip and so can be easily turned off.

I'm switching it on tonight to try and get at least one run through
various folks' performance suites in case SPEC or something else has
serious issues with it. I'll watch bots and revert if anything shows up.

supported by target (they are R2 instructions).

cc85160672 Continue cleanup of LIT, getting rid of the remaining artifacts from dejagnu 
* Removed test/lib/llvm.exp - it is no longer needed 
* Deleted the dg.exp reading code from test/lit.cfg. There are no dg.exp files
  left in the test suite so this code is no longer required. test/lit.cfg is
  now much shorter and clearer 
* Removed a lot of duplicate code in lit.local.cfg files that need access to
  the root configuration, by adding a "root" attribute to the TestingConfig
  object. This attribute is dynamically computed to provide the same
  information as was previously provided by the custom getRoot functions. 
* Documented the config.root attribute in docs/CommandGuide/lit.pod
