Document which relocation records are static and dynamic.

There are two versions of to_string used by TestRunner.py. The one defined 
in TestRunner.py and the one defined in utils/lit/lit/util.py. The util.py
version is superior to the TestRunner.py version.

This change removes the duplicate to_string in TestRunner.py in favor of
always using the version from util.py. Beside removing duplicate code, this
makes it easier to debug TestRunner.py since only one version of to_string
is used.

Summary:
508   root node entries (root_limit)
510   internal node entries (node_limit)

For a filename with 40 bytes, its sizeof(ext4_dir_entry_2) = 48, a linear directory can contain at most floor(4096/48)=85 of them.
The real per-directory entry limit should be 508*510*85 = 22021800
The limit varies with the average length of filenames.

However, the Linux ext4 code does not try rebalancing the htree, so we will not be able to create filenames in a full leaf node. This is demonstrated with the following example, certain filenames cannot be used while others can:

  % touch d/0000000000000000000000000000000000816a6f
  touch: cannot touch 'd/0000000000000000000000000000000000816a6f': No
  space left on device
  % touch d/0000000000000000000000000000000000816a70
  # succeeded

This is a test for a transform that was suggested in the post-commit
mailing list thread for rL329821. The target in question is not in
trunk, so PPC gets to stand in for it because it's the only in-tree
target that sets 'isFPExtFree()' to 'true'.

opt-bisect shouldn't skip these passes; they lower intrinsics which
no other pass can handle.

I'm told the repeat of "500000, 600000," is accidental, and should be

Summary:
llvm-diff incorrectly reports that there's a diff when input IR contains undef/zeroinitializer/constantvector/indirectbr.
(This happens even if two identical files are given, e.g. `llvm-diff x.ll x.ll`)

This is fix to the bug report https://bugs.llvm.org/show_bug.cgi?id=33623 .

This is a code size win in code that takes offseted addresses
frequently, such as C++ constructors that typically need to compute
an offseted address of a vtable. This reduces the size of Chromium
for Android's .text section by 108KB.

This lifts a restriction on DILocation::getMergedLocation(), allowing it
to create merged locations for instructions other than calls.

Instruction::applyMergedLocation() now defaults to creating merged
locations for all instructions.

The default behavior of getMergedLocation() is unchanged: callers which
invoke it directly are unaffected.

This change will enable a follow-up Mem2Reg fix which improves crash
reporting.

Summary:
GCC compresses the pseudo instruction "mv rd, rs",  which is an alias of
"addi rd, rs, 0", to "c.mv rd, rs".

In LLVM we rely on the canonical MC instruction (MCInst) to do our compression
checks and since there is no rule to compress "addi rd, rs, 0" --> "c.mv
rd, rs" we lose this compression opportunity to gcc.

 In this patch we fix that by adding an addi to c.mv compression pattern, the
 instruction "mv rd, rs" will be compressed to "c.mv rd, rs" just like
 gcc does.

Patch by Zhaoshi Zheng (zzheng) and Sameer (sabuasal).

AFI->setRedZone(false) was put in the wrong place before, and so it only fired
on functions that didn't have stack frames. This moves that to the top of
emitPrologue to make sure that every function without a redzone has it set
correctly.

This also adds a function representing one of the early exit cases (GHC calling
convention) to the MachineOutliner noredzone test to ensure that we can outline
from functions like these, where we never use a redzone.

There are cases when individual NodeSets can be equal with respect to
the ordering criteria. Since they are stored in an ordered container,
use stable_sort to preserve the relative order of equal NodeSets. 

This should remove non-determinism discovered by shuffling done in
llvm::sort with expensive checks enabled.
