* Define CMAKE_ARM_COMPILER automatically (#469)
Makes use of CMAKE_SYSTEM_PROCESSOR to detect whether compilation is happening for an ARM architecture.
* Use the correct guard for specifying msse2 compiler flags.
Bruteforce and conversions were only checking against ANDROID which was not sufficient for ARM Linux builds.
* Remove redundant uses of the msse2 compiler flag.
* Globally set -msse2 for x86/amd64 gcc, Apple and Clang builds.
This is a change in behaviour. Prior to this commit, msse2 was only set for bruteforce and conversions.
msse and mfpmath=sse were already set globally prior to this change.
In all these cases, the new entrypoint is not necessary. These
changes enable the tests to work or are a necessary step to get
the tests to work on an OpenCL 1.2 implementation.
While this may not be the final approach we want to solve this
specific compatibility issue, it also has the nice property of
reducing the diff with cl12_trunk until we merge.
