Switch the asmprinter (.ll) and all the stuff it requires over to

use raw_ostream instead of std::ostream. Among other goodness,
this speeds up llvm-dis of kc++ with a release build from 0.85s
to 0.49s (88% faster).
Other interesting changes:
1) This makes Value::print be non-virtual.
2) AP[S]Int and ConstantRange can no longer print to ostream directly,
use raw_ostream instead.
3) This fixes a bug in raw_os_ostream where it didn't flush itself
when destroyed.
4) This adds a new SDNode::print method, instead of only allowing "dump".
A lot of APIs have both std::ostream and raw_ostream versions, it would
be useful to go through and systematically anihilate the std::ostream
versions.
This passes dejagnu, but there may be minor fallout, plz let me know if
so and I'll fix it.

Rework the routines that convert AP[S]Int into a string. Now, instead of
...
returning an std::string by value, it fills in a SmallString/SmallVector
passed in. This significantly reduces string thrashing in some cases.
More specifically, this:
- Adds an operator<< and a print method for APInt that allows you to
directly send them to an ostream.
- Reimplements APInt::toString to be much simpler and more efficient
algorithmically in addition to not thrashing strings quite as much.
This speeds up llvm-dis on kc++ by 7%, and may also slightly speed up the
asmprinter. This also fixes a bug I introduced into the asmwriter in a
previous patch w.r.t. alias printing.

Also, change it to use explicit Size and Align parameters, allowing

alignment requirement.

Reimplement MemoryBuffer::getFile with three enhancements:
...
1) stop using MappedFile.
2) if profitable use the sys::path::MapInFilePages api to
read the file.
3) otherwise fallback to read.
When sys::path::MapInFilePages is implemented, this provides
several benefits:
#1 : this avoids fragmenting memory for small files.
#2 : this avoids extraneous stat calls when the file size is known.
#3 : this only keeps the file descriptor open while reading the
file, not for the duration of the lifetime of the memory
buffer. This fixes a serious clang FD 'leak' problem.
I believe that this will work on a win32 machine, but I don't have
one to test on. I'd appreciate it if someone could check.

Fix a typo. It's causing consumer-typeset to miscompile. Perhaps more.

Add support to APInt for shift and rotate operations with APInt
...
instead of uint32_t for the shift/rotate count operand type.

invalid command-line options.

Unbreak build with gcc 4.3: provide missed includes and silence most annoying warnings.

901540f118
Fixed bug in APInt::Profile() where the BitWidth field was not included in the
...
profile of the APSInt object. This caused unexpected Profile collisions where
none should have occurred.

d66c791904
Fixed bug in FoldingSetIteratorImpl where we did not correctly check if
...
we had reached the "fake bucket" after the last bucket, allowing the iterator
in some cases to run off the end of the hashtable.

Fix a warning about comparison between signed and unsigned,
...
being consistent with the rest of the APInt implementation.

Add countTrailingOnes member functions to APInt.

6f30a0798f
Added "Profile" method to APFloat for use with FoldingSet.
...
Added member template "Add" to FoldingSetNodeID that allows "adding" arbitrary
objects to a profile via dispatch to FoldingSetTrait<T>::Profile().
Removed FoldingSetNodeID::AddAPFloat and FoldingSetNodeID::APInt, as their
functionality is now replaced using the above mentioned member template.

Add support to FoldingSet for hashing APInt objects.

Added "bucket_iterators" to FoldingSet. Bucket iterators allow iteration
...
over all the nodes in a particular bucket.
