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).

StringRef tweaks:

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.

Workaround PR5482, because all the gcc versions that I had were miscompiling StringRef:
...
4.2.4, 4.3.4, 4.4.2.
The workaround is to use a local min/max implementation that takes an integer
param, and not a reference to integer param (like std::min does).
