Remove SmallString::append_*int* methods; how many copies of int -> str
...
conversion code do we really need?
- S.append_uint(N) can be replaced with 'raw_svector_ostream(S) << N' which is
somewhat slower due to the extra set up cost, but still plenty fast
(especially if the svector set up cost can be amortized).

Change raw_svector_ostream to reserve the input buffer if necessary, Ted was
...
right.
- This class turns out to be much more convenient to use if we do this; clients
can make sure the buffer is always big enough if they care (since our current
idiom tends to be to use a SmallString<256> for the input to this we should
generally be avoiding an unnecessary malloc).
Also, add a convenience raw_svector_ostream::str method which flushes the buffer
and returns a StringRef for the vector contents.

Canonicalize indices in a constantexpr GEP. If Indices exceed the

static extents of the static array type, it causes GlobalOpt and

Fix gcc-4.4/fedora 11 by adding a sentinel value to SimpleValueType.
