[PATCH] [CodeGen] Properly support the half FP type with non-native operations (-fallow-half-args-and-returns)

[Oliver Stannard]

You have marked this as depending on http://reviews.llvm.org/D4602, but this patch includes all of the changes from http://reviews.llvm.org/D4602, is this intentional?

This patch changes the behaviour for half<->int conversions, but I only see a test the for half->int direction. Could you add some more?
