Final patch in series, adds new tests of the REV Neon Intrinsics for ARM. These 
tests subsume the autogenerated tests in gcc/testsuite/gcc.target/arm/neon (that 
only check assembler output) by also checking the execution results, reusing the 
test bodies introduced into AArch64 in the first patch.

Testsuite driver simd.exp from 
http://gcc.gnu.org/ml/gcc-patches/2014-03/msg01500.html, will ensure that's 
committed first.

All passing on arm-none-eabi.
