Juneyoung Lee 39eb2665d9 [InstCombine] Add a few more patterns for folding select of select 
This is a patch that folds select of select to salvage some optimizations after select -> and/or folding is disabled.

```
select (select a, true, b), c, false -> select a, c, false
select c, (select a, true, b), false -> select c, a, false
  if c implies that b is false (isImpliedCondition).
```
https://alive2.llvm.org/ce/z/ANatjt, https://alive2.llvm.org/ce/z/rv8zTB

```
sel (sel c, a, false), true, (sel !c, b, false) -> sel c, a, b
sel (sel !c, a, false), true, (sel c, b, false) -> sel c, b, a
```

This directory contains test cases for the instcombine transformation.  The
dated tests are actual bug tests, whereas the named tests are used to test
for features that the this pass should be capable of performing.
