the case where a specific range is replaced by new text. Previously,
the calculation would shift any position from within a replaced region
to the first character after the region. This is undersirable, e.g. for
clang-format's include sorting.

One problem in clang-tidy and other clang tools face is that there is no
way to lookup an arbitrary name in the AST, that's buried deep inside Sema
and might not even be what the user wants as the new name may be freshly
inserted and not available in the AST.
A common use case for lookups is replacing one nested name with another
while minimizing namespace qualifications, so replacing 'ns::foo' with
'ns::bar' will use just 'bar' if we happen to be inside the namespace 'ns'.
This adds a little helper utility for exactly that use case.

It took me some time to figure out why this is not working as expected:
std:error_code converts to true if there is an error. This means we never
ever took the generated absolute path, which happens to be the right thing
anyways as it properly works with virtual files. Just remove the whole
thing, relative paths are covered by existing tooling tests.

To implement this nicely, add a function that merges two sets of
replacements that are meant to be done in sequence. This functionality
will also be useful for other applications, e.g. formatting the result
of clang-tidy fixes.

insertions. It is unlikely to be the intention to delete parts of newly
inserted code. To do so, changed sorting Replacements at the same offset
to have decreasing length.

The default language options will lead to incorrect replacements in C++
code, for example when trying to replace nested name specifiers ending
in "::".

This moves classes for storing and applying replacements to separate
files. These classes specifically are used by clang-format which doesn't
have any other dependencies on clangAST. Thereby, the size of
clang-format's binary can be cut roughly in half and its build time sped
up.
