82d96cccbc Grow BumpPtrAllocator's slab size dynamically if we allocated many slabs. This
reduces the amount of malloc calls and may reduce memory overhead.

32cda119ef Add a new isSignWrappedSet() method to ConstantRange.
Fix zeroExtend and signExtend to support empty sets, and to return the smallest
possible result set which contains the extension of each element in their
inputs. For example zext i8 [100, 10) to i16 is now [0, 256), not i16 [100, 10)
which contains 63446 members.

d4c454317a Make tool_output_file's raw_ostream instance a member variable instead
of a base class.

the file is done. Also, this eliminates the need for
formatted_tool_output_file.

12881e79b6 Remove a hack that tries to understand incorrect triples from the
Triple class constructor.  Only valid triples should now be used
inside LLVM - front-ends are now responsable for rejecting or
correcting invalid target triples.  The Triple::normalize method
can be used to straighten out funky triples provided by users.
Give this a whirl through the buildbots to see if I caught all
places where triples enter LLVM.

- On my core2 this code is faster except when the checked string was very short
  (smaller than the list of delimiters).

93d81b697c Fix the rest of rdar://8318441 which happens when a raw_fd_ostream
(e.g. errs()) fails in close() due to (e.g.) a broken pipe.  As
previously written, the had_error() flag would get set and then
the raw_ostream dtor would report a fatal error.  There is nothing
the client can do about this and we have no way to report the error,
so just eat it.

335db22392 Add a 'normalize' method to the Triple class, which takes a mucked up
target triple and straightens it out.  This does less than gcc's script
config.sub, for example it turns i386-mingw32 into i386--mingw32 not
i386-pc-mingw32, but it does a decent job of turning funky triples into
something that the rest of the Triple class can understand.  The plan
is to use this to canonicalize triple's when they are first provided
by users, and have the rest of LLVM only deal with canonical triples.
Once this is done the special case workarounds in the Triple constructor
can be removed, making the class more regular and easier to use.  The
comments and unittests for the Triple class are already adjusted in this
patch appropriately for this brave new world of increased uniformity.
