Do not inline VLA functions

When VLA function is inlined, "hasVLA" attribute is lost and alloca
cannot be resolved properly. This behavior can result in segfault.

 Support opaque pointers in PromoteBools pass

PromoteBools was wrongly skipping RAUW operation on ptr function calls
after promoting their signature and adding their users to promotion
queue which lead to cleaning those users and creating undef values in
subsequent users, which then in turn created dead code which was
eliminated and caused wrong test results. Essentially this pass was
wrongly skipping RAUW when neccessary.

In cases like these:
```llvm
  @call = call ptr @some-function(i1 true)
  @bitcast = bitcast ptr @call to ptr
  @ptrtoint = ptrtoint ptr @bitcast to i64
```

After pass pre fix:
```llvm
  @0 = call ptr @some-function(i8 1)
  @ptrtoint = ptrtoint ptr undef to i64
```

Proper pass behaviour:
```llvm
  @0 = call ptr @some-function(i8 1)
  @bitcast = bitcast ptr @0 to ptr
  @ptrtoin = ptrtoint ptr @bitcast to i64
```
