Remove some remnants from WIVectorize.
Add initial support for MIPS.

At this point ./configure can complete successfully.
Make config/xclang respect --host and --build.

This allows us to use --host and --build to work around a bug in LLVM's
handling of mips* and mips64* triples. Currently, triples have an effect on
the output ELF that should be based on the ABI instead.
Make clang++ checks in configure.ac respect --host
Lower address spaces for Mips.

This fixes example1 (except SPIR variants), example2, and example2a among
others.
Merge branch 'mips' of github.com:dsandersimgtec/pocl
Added cross platform compatible script for finding hwloc library.
Added support to FindHwloc.cmake for Hwloc_CFLAGS and Hwloc_LDFLAGS

Now script also creates Hwloc_CFLAGS and Hwloc_LDFLAGS variables where include and library directories are already in compiler switch format instead of cmake lists.
Fixed setting Hwloc include directories as list instead of string to prevent error with empty list.
