Remove bounded StringRef::compare() since nothing but Clang SA was using it and it is just as easy to use StringRef::substr() preceding StringRef::compare() to achieve the same thing.

zextOrTrunc(), and APSInt methods extend(), extOrTrunc() and new method

Avoid O(n*m) complexity in StringRef::find_first(_not)_of(StringRef).
...
- Cache used characters in a bitset to reduce memory overhead to just 32 bytes.
- On my core2 this code is faster except when the checked string was very short
(smaller than the list of delimiters).

Add an override to StringRef::getAsInteger which parses into an APInt.
...
It gets its own implementation totally divorced from the (presumably
performance-sensitive) routines which parse into a uint64_t.
Add APInt::operator|=(uint64_t), which is situationally much better than
using a full APInt.
