  [Clang][Test] Add llvm-lto, llvm-lto2 and llvm-profdata to the tool substitutions list

Similar to issue fixed in D107155, some lit tests invoke `llvm-lto`,
`llvm-lto2` and `llvm-profdata` without going through the substitution
system. While the test runner correctly picks up these binaries from
the build directory, it doesn't print its absolute path. When copying
the invocations when reproducing test failures, this can result in
`command not found: llvm-lto` or other errors (caused by using wrong
version of the tool).

This patch adds these tools to the `tools` variable in
`clang/test/lit.cfg.py` which will then call add_tool_substitutions.

  -----------
  [LoongArch] Make use of addu16i.d for adds with suitable immediates

Ideally `addu16i.d` could be paired with `{ld,st}ptr` for faster memory
accesses with 32-bit-aligned offsets (it was designed for this purpose),
but it would require more work and the original use case (GP-relative
accesses) does not exist any more with the current LoongArch psABI.

It could still be used for accelerating additions of certain constants
though, which is what this patch intends to do.
