f34c3ca304 Add {start,end}with_lower methods to StringRef.
startswith_lower is ocassionally useful and I think worth adding.
endwith_lower is added for completeness.

e4a4aecffb Commit a no-op change to StringRef to (hopefully) trigger build bots.
r187874 seems to have been missed by the build bot infrastructure, and
the subsequent commits to compiler-rt don't seem to be queuing up new
build requsets. Hopefully this will.

As it happens, having the space here is the more common formatting. =]

255f89faee Sort the #include lines for the include/... tree with the script.
AKA: Recompile *ALL* the source code!

This one went much better. No manual edits here. I spot-checked for
silliness and grep-checked for really broken edits and everything seemed
good. It all still compiles. Yell if you see something that looks goofy.

250eb005d9 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).

1e7ad3993d 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.

2fe05d80d3 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).
