The x86-64 "avx" feature changes how >128 bit vector types are passed, instead of being passed in separate 128 bit registers, they can be passed in 256 bit registers. "avx512f" does the same thing, except it switches from 256 bit registers to 512 bit registers. The result of both of these is an ABI incompatibility between functions compiled with and without these features. This patch implements a warning/error pair upon an attempt to call a function that would run afoul of this. First, if a function is called that would have its ABI changed, we issue a warning. Second, if said call is made in a situation where the caller and callee are known to have different calling conventions (such as the case of 'target'), we instead issue an error.
