string_ostream is a safe and efficient string builder that combines opaque
stack storage with a built-in ostream interface.
small_string_ostream<bytes> additionally permits an explicit stack storage size
other than the default 128 bytes to be provided. Beyond that, storage is
transferred to the heap.
This convenient class can be used in most places an
std::string+raw_string_ostream pair or SmallString<>+raw_svector_ostream pair
would previously have been used, in order to guarantee consistent access
without byte truncation.
The patch also converts much of LLVM to use the new facility. These changes
include several probable bug fixes for truncated output, a programming error
that's no longer possible with the new interface.

This should make sure that most new uses use the std prefix.

Remove the use of the std::function and replace the capturing lambda with a
non-capturing one, opting to pass the user data down to the context. This is
needed as std::function is not yet available on all hosted platforms (it
requires RTTI, which breaks on Windows).
Thanks to Nico Rieck for pointing this out!

Move the implementation of the Win64 EH printer from the COFFDumper into its own
class. This is in preparation for adding support to print ARM EH information.
The only real change here is in printUnwindInfo where we now lambda lift the
implicit this parameter for the resolveFunction. Also setup the printing to
handle ARM. This now has set the stage to introduce ARM EH printing.
