[PowerPC] Exploit vabsd on P9

Summary: Exploit vabsd* for for absolute difference of vectors on P9,
for example:
void foo (char *restrict p, char *restrict q, char *restrict t)
  for (int i = 0; i < 16; i++)
     t[i] = abs (p[i] - q[i]);
this case should be matched to the HW instruction vabsdub.

Improve SmallPtrSetImpl::count implementation

Relying on the find method implies a roundtrip to the iterator world, which is
not costless because iterator creation involves a few check to ensure the
iterator is in a valid position (through the SmallPtrSetIteratorImpl::AdvanceIfNotValid
method). It turns out that the result of SmallPtrSetImpl::find_imp is either
valid or the EndPointer, so there's no need to go through that abstraction,
and the compiler cannot guess it.

[DebugInfo][CallSites] Remove decl subprograms from 'retainedTypes:'

After the D70350, the retainedTypes: isn't being used for the purpose
of call site debug info for extern calls, so it is safe to delete it
from IR representation.
We are also adding a test to ensure the subprogram isn't stored within
the retainedTypes: from corresponding DICompileUnit.
