  [libTooling] Add flag to getRangeForEdit to ignore macro expansions

This commit resolves the FIXME around the behavior of
`Lexer::makeFileCharRange` that `getRangeForEdit` inherits around
source locations in macro expansions.

We add a flag to `getRangeForEdit` that allows a caller to disable the
behavior, and instead uses the spelling location instead, with checks
to ensure that the source locations are not within a macro definition.
