[ThinLTO] Option to control path of distributed backend files Summary: Add support to control where files for a distributed backend (the individual index files and optional imports files) are created. This is invoked with a new thinlto-prefix-replace option in the gold plugin and llvm-lto. If specified, expects a string of the form "oldprefix:newprefix", and instead of generating these files in the same directory path as the corresponding bitcode file, will use a path formed by replacing the bitcode file's path prefix matching oldprefix with newprefix. Also add a new replace_path_prefix helper to Path.h in libSupport. Depends on D19636.

; Check that changing the output path via prefix-replace works
[ThinLTO] XFAIL path manipulation test on Windows This test is creating and checking paths using '/'. XFAIL it on Windows to unbreak bot: http://lab.llvm.org:8011/builders/llvm-clang-lld-x86_64-scei-ps4-windows10pro-fast/builds/5478 llvm-svn: 269775

; Use of '/' in paths created here make this unsuitable for Windows.
[llvm] Get rid of "%T" expansions The %T lit expansion expands to a common directory shared between all the tests in the same directory, which is unexpected and unintuitive, and more importantly, it's been a source of subtle race conditions and flaky tests. In https://reviews.llvm.org/D35396, it was agreed that it would be best to simply ban %T and only keep %t, which is unique to each test. When a test needs a temporary directory, it can just create one using mkdir %t. This patch removes %T in llvm. Differential Revision: https://reviews.llvm.org/D36495 llvm-svn: 310953
