Summary:
Currently, BranchFolder drops DebugLoc for branch instructions in some places. For example, for the test code attached, the branch instruction of 'entry' block has a DILocation of
```
!12 = !DILocation(line: 6, column: 3, scope: !11)
```
, but this information is gone when then block is lowered because BranchFolder misses it. This patch is a fix for this issue.

Using the constructed name for the class properties with dot syntax may
yield an inappropriate selector (i.e. if it is specified via property
attributes). Prefer the declaration for the selector, falling back to
the constructed name otherwise.

This is currently the minimum required version by LLVM. Since LLVM is
needed to build Polly, we also require at least that version.

isl headers are currently missing in a Polly installation. Because the
Polly headers depend on those, code can't be compiled against an
installed Polly.
This patch installs the isl headers. I left a TODO, as optionally it
should be possible to use a system version of isl instead of the one
shipped with Polly.
When compiling, clients of the installation need to add
-I${PREFIX}/include/polly/ to there include path right now, because
there currently is no way to export this path automatically.

Pull out repeated code for extraction index operand and source vector value type.
Use isNullConstant helper to check for zero extraction index.
llvm-svn: 295670
Summary:
Each OperandPredicateMatcher shouldn't need to know how to generate the expression
to reference a MachineOperand. The OperandMatcher should provide it.
In addition to separating responsibilities, this also lays some groundwork for
decoupling source patterns from destination patterns to allow invented operands
or operands provided by GlobalISel's equivalent to the ComplexPattern<> class.

There used to be a check in the IRTranslator that prevented us from having to
deal with atomic loads/stores. That check has been removed in r294993 and the
AArch64 backend was updated accordingly. This commit does the same thing for the
ARM backend.
In general, in the ARM backend we introduce fences during the atomic expand
pass, so we don't have to worry about atomics, *except* for the 32-bit ARMv8
target, which handles atomics more like AArch64. Since we don't want to worry
about that yet, just bail out of instruction selection if we find any atomic
loads.

Its more profitable to go through memory (1 cycles throughput)
than using VMOVD + VPERMV/PSHUFB sequence ( 2/3 cycles throughput) to implement EXTRACT_VECTOR_ELT with variable index.
IACA tool was used to get performace estimation (https://software.intel.com/en-us/articles/intel-architecture-code-analyzer)
For example for var_shuffle_v16i8_v16i8_xxxxxxxxxxxxxxxx_i8 test from vector-shuffle-variable-128.ll I get 26 cycles vs 79 cycles.
Removing the VINSERT node, we don't need it any more.

Summary:
I originally set out to move the NameMatches closer to the relevant
function and add some unit tests. However, in the process I've found a
couple of bugs in the implementation:
- the early exits where not always correct:
- (test==pattern) does not mean the match will always suceed because
of regular expressions
- pattern.empty() does not mean the match will fail because the "" is
a valid prefix of any string
So I cleaned up those and added some tests. The only tricky part here
was that regcomp() implementation on darwin did not recognise the empty
string as a regular expression and returned an REG_EMPTY error instead.
The simples fix here seemed to be to replace the empty expression with
an equivalent non-empty one.

This change moves the SymbolBodies with isLocal() == true before the global
symbols then calculating NumLocals rather than assuming all locals are
added before globals and the first NumLocals have isLocal() == true. This
permits Thunks to be moved after the pass that adds global symbols from
synthetics to the symbol table.
