Update piglit reference to match the latest master.
Store the sorted version.
Updated piglit reference file to the latest commit in piglit.
Made the sorting of the reference more stable by fixing the
locale used.
Some the AMD tests fail to build in case having a 'wrong' version of GL (happens in Ubuntu 14.04). Build the ones that can be built by using -k switch to the make.
Remove references to the old WIVectorizer as it's deprecated and
probably breaks with LLVM 3.5.
Use size_t to avoid ambiguous Buffer ctor error with Clang 3.4.
Skip AMD 2.9's NBody, Mandelbrot, and BinomialOptionMultiGPU if
they were not built (due to incompatible GL, for example).
XFAIL the vector kernel args test also if _DEBUG is set.
LLVM 3.4: compiling blocks crashes Clang with multiple address
spaces. The patch fixes this. Will be submitting upstream.
Move PHINodes from the entries of the replicated
parallel regions to the entry of the first of the chain.

Fixes a regression test case that broke with LLVM 3.5 due to
this exposed bug.
Updated some interesting CHANGES from git log.
Add -pthread to LDFLAGS otherwise some tests fail to link
when compiling with some compilers such as Clang++ 3.4 or gcc 4.8.
Merge branch 'master' of github.com:pocl/pocl into pocl-llvm-3.5
