[PATCH] D12856: Always promote f16

[Oliver Stannard via llvm-commits]

Updated to correctly handle FPEXT, and get test/CodeGen/ARM/fp16-promote.ll passing. The changes in SelectionDAGBuilder.cpp were required for a few of the test cases, notably those with half-precision arguments (which the clang frontend doesn't currently emit, at least for ARM), and phi nodes.
