"[SLP] Generalization of stores vectorization."
 "[SLP] Fix -Wunused-variable. NFC"
 "[SLP] Vectorize jumbled stores."

As they're causing significant (10-30x) compile time regressions on
vectorizable code.

The primary cause of the compile-time regression is f228b5371647f471853c5fb3e6719823a42fe451.

0b89a0ccd6 [SLP] Generalization of stores vectorization.
Stores are vectorized with maximum vectorization factor of 16. Patch
tries to improve the situation and use maximal vectorization factor.

de70987193 [CostModel][X86] Fix SLM <2 x i64> icmp costs
SLM is 2 x slower for <2 x i64> comparison ops than other vector types, we should account for this like we do for SLM <2 x i64> add/sub/mul costs.

This should remove some of the SLM codegen diffs in D43582

a62270de2c Revert "Temporarily Revert "Add basic loop fusion pass.""
The reversion apparently deleted the test/Transforms directory.

Will be re-reverting again.

71d1cca7ef Temporarily Revert "Add basic loop fusion pass."
As it's causing some bot failures (and per request from kbarton).

This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda.

a9632ac602 [TTI] Add generic UADDSAT/USUBSAT costs
Add generic costs calculation for UADDSAT/USUBSAT intrinsics, this fallbacks to using generic costs for uadd_with_overflow/usub_with_overflow + a select.
