Simon Pilgrim 9eab73fa17 [X86] Update SSE/AVX integer MINMAX intrinsics to emit llvm.smax.* etc. (PR46851) 
We're now getting close to having the necessary analysis/combines etc. for the new generic llvm smax/smin/umax/umin intrinsics.

This patch updates the SSE/AVX integer MINMAX intrinsics to emit the generic equivalents instead of the icmp+select code pattern.

Simon Pilgrim 2239882f7d [CodeGen][X86] Move x86 builtin intrinsic/codegen tests into X86 subfolder. 
There are still plenty of tests that specify x86 as a triple but most shouldn't be doing anything very target specific - we can move any ones that I have missed on a case by case basis.
