b6e6dd63ad 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.

69bc985550 Teach APFloat how to create both QNaNs and SNaNs and with arbitrary-width 
payloads.  APFloat's internal folding routines always make QNaNs now,
instead of sometimes making QNaNs and sometimes SNaNs depending on the
type.

94cdac52e5 Adding the MicroBlaze backend. 
The MicroBlaze is a highly configurable 32-bit soft-microprocessor for
use on Xilinx FPGAs. For more information see:
http://www.xilinx.com/tools/microblaze.htm
http://en.wikipedia.org/wiki/MicroBlaze

The current LLVM MicroBlaze backend generates assembly which can be
compiled using the an appropriate binutils assembler.

lookup is that if the lookup key is contained in the key, we return the data.

5db856d384 Introduce Twine::toStringRef, a variant of toVector which avoids the copy if the 
twine can be represented as a single StringRef. Use the new methode to simplify
some twine users.

9c1ca33ac3 add new isSingleStringRef()/getSingleStringRef() methods to twine, 
and use them to avoid a copy of a string in getNameWithPrefix in
the common case.  It seems like Value::setName and other places 
should use this as well?

cdbc36f961 Reimplement getToken and SplitString as "StringRef helper functions" 
- getToken is modeled after StringRef::split but it can split on multiple
  separator chars and skips leading seperators.
- SplitString is a StringRef::split variant for more than 2 elements with the
  same behaviour as getToken.

090f279ac5 Add a SmallBitVector class, which mimics BitVector but uses only 
a single pointer (PointerIntPair) member. In "small" mode, the
pointer field is reinterpreted as a set of bits. In "large" mode,
the pointer points to a heap-allocated object.

Also, give BitVector empty and swap functions.

And, add some simple unittests for BitVector and SmallBitVector.

c71c44ec7f Add accessors for the largest-magnitude, smallest-magnitude, and 
smallest-normalized-magnitude values in a given FP semantics.
Provide an APFloat-to-string conversion which I am quite ready to admit could
be much more efficient.
