Backport -ftime-trace from upstream llvm & clang (#4873) 
* Backport -ftime-trace from upstream llvm & clang

This change back-ports the -ftime-trace feature implemented by Aras
Pranckevičius (@aras-p) into DXC.

Aras has a great blog post describing the motivaiton for this feature
and how to use it (see:
https://aras-p.info/blog/2019/01/16/time-trace-timeline-flame-chart-prof
iler-for-Clang/).

As shaders are getting more and more complex we need better timing data
for ourselves as compiler writers and our users as HLSL writers to know
how to improve compile times of complex shaders.

This implementation is a starting point to give us data to help drive
our efforts to improve compile-time performance.

Because DXC's LLVM is very far removed from the version of LLVM the
patch was originally written for this change is not strictly a
cherry-pick of
https://github.com/llvm/llvm-project/commit/d880de2d19d46f7cfea7aa593602
458440bc1e8d. Instead this change is a manually applied and
reconstructed patch with significant alterations along the way. The
alaterations are performed by myself, but credit for the patch remains
with @aras-p.
