Alexey Bataev 4a5bb772c3 [OPENMP] Codegen for 'firstprivate' clause.
This patch generates some helper variables that used as private copies of the corresponding original variables inside an OpenMP 'parallel' directive. These generated variables are initialized by copy using values of the original variables (with the copy constructor, if any). For arrays, initializator is generated for single element and in the codegen procedure this initial value is automatically propagated between all elements of the private copy.
In outlined function, references to original variables are replaced by the references to these private helper variables. At the end of the initialization of the private variables an implicit barier is generated by calling __kmpc_barrier(...) runtime function to be sure that all threads were initialized using original values of the variables.

Hal Finkel 92e31a5ead Add getOpenMPSimdDefaultAlignment for PowerPC
When the aligned clause of an OpenMP simd pragma is not provided with an
explicit alignment, a target-dependent default must be used. This adds such a
default of PPC targets.

This will become slightly more complicated when BG/Q support is added (because
then it will depend on the type). For now, 16 is a correct value for all
systems, and covers Altivec and VSX vectors.

Alexander Musman a5f070aec0 [OPENMP] Loop collapsing and codegen for 'omp simd' directive.
This patch implements collapsing of the loops (in particular, in
presense of clause 'collapse'). It calculates number of iterations N
and expressions nesessary to calculate the nested loops counters
values based on new iteration variable (that goes from 0 to N-1)
in Sema. It also adds Codegen for 'omp simd', which uses
(and tests) this feature.

Eli Bendersky b198b4e864 Rename loop unrolling and loop vectorizer metadata to have a common prefix.
[Clang part]

These patches rename the loop unrolling and loop vectorizer metadata
such that they have a common 'llvm.loop.' prefix.  Metadata name
changes:

llvm.vectorizer.* => llvm.loop.vectorizer.*
llvm.loopunroll.* => llvm.loop.unroll.*

This was a suggestion from an earlier review
(http://reviews.llvm.org/D4090) which added the loop unrolling
metadata. 

Patch by Mark Heffernan.

For namespaces, this is consistent with mangling and GCC's debug info

consistency between all anonymous entities but don't want to confuse
them with template arguments, etc, so we'll just go with parens in all

Alp Toker 1d8362cd19 Enhance OpenMP parser tests from r197553 / r197598
Move some of the verifier directives away from the end of the pragma line.

This ensures that the diagnostics relate to the trailing token being tested and
not the verifier comments which are themselves part of the token stream.

Alp Toker b14a4709f5 Fix OpenMP recovery with trailing tokens following the pragma
The recovery was failing due to a missing case in SkipUntil().

Also add back tests from r197553 that were reverted in the previous commit.

Alp Toker d751fa7868 Revert "[OPENMP] Fix for parsing OpenMP directives with extra braces, brackets and parens"
These parser changes were redundant. The same or better recovery can be
achieved with a one-line fix to SkipUntil() due to land in the next commit.

This reverts commit r197553.

Alp Toker 6731f38aca Fix a test that was never being run, mark it XFAIL
Turns out this has always been crashing since the test landed in
r186647:

  Assertion failed: (Access != AS_none && "Access specifier is AS_none inside a record decl"), function CheckAccessDeclContext, file clang/lib/AST/DeclBase.cpp, line 690.

Needs attention.

Chandler Carruth 0153800601 Add initial rough support for synthesizing linker options when passed
-fopenmp in the link step on Linux. There is probably more tweaking that
will need to take place to get good support for linking the relevant
libraries on all Linux distributions and/or on other platforms, but this
get's the ball moving and allows Clang to build programs which contain
OpenMP pragmas that can be safely ignored by a compiler that doesn't
implement them, and yet makes direct calls into the OpenMP runtime.
