Manuel Jacob a7c48f99ae CodeGenPrep: sink extends of illegal types into use block. 
Summary:
This helps the instruction selector to lower an i64 * i64 -> i128
multiplication into a single instruction on targets which support it.

This is an update of D2973 which was reverted because of a bug reported

Tim Northover d495642c54 X86: move test requiring X86TargetLowering info into its own directory 
If LLVM is built without X86 as a supported target then the test would
