Simon Pilgrim 25fb4177fb [X86][SSE] Reapplied: Simplify vector LOAD + EXTEND on pre-SSE41 hardware 
Improve vector extension of vectors on hardware without dedicated VSEXT/VZEXT instructions.

We already convert these to SIGN_EXTEND_VECTOR_INREG/ZERO_EXTEND_VECTOR_INREG but can further improve this by using the legalizer instead of prematurely splitting into legal vectors in the combine as this only properly helps for lowering to VSEXT/VZEXT.

Removes a lot of unnecessary any_extend + mask pattern - (Fix for PR25718).

Reapplied with a fix for PR26953 (missing vector widening legalization).
