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).

Simon Pilgrim 60228bdb80 [X86] Regenerated + extended widened vector conversion tests 
- Ensure we test X86 + X64
- sitopfp / uitofp requires testing for SSE2 and SSE42 as well (part of the fix for PR26953)

Simon Pilgrim b504263e4a [X86][SSE] Sign extension for target vector sizes less than 128 bits (pt2) 
Add support for v2i8/v2i16 to v2f64 by using a sign extension to v2i32 before conversion to v2f64.

Chris Lattner ff392ab3ed now that generic vector types aren't selected onto MMX registers, these 
tests don't need -disable-mmx.
