%T has been deprecated for about seven years since it is not unique to
each test and can thus lead to races. This patch removes uses of %T from
clang-tools-extra with the eventual goal of removing support for %T from
lit.
The tool now supports a collection of arguments to turn on and provide settings
for the formatting of code affected by applying replacements:
* --format turns on formatting (default style is LLVM)
* --style controls code style settings
* --style-config allows one to explicitly indicate where a style config file
lives.
The libclangApplyReplacements interface has a new function to turn Replacements
into Ranges to be used with tooling::reformat().
