[libc] Add printf error handling (with fixes) ( #166382 )
...
https://github.com/llvm/llvm-project/issues/159474
Resubmitting https://github.com/llvm/llvm-project/pull/162876 with fixes
as it broke some buildbots:
- Fix comparisons of integer expressions of different signedness
- Not check for specific errnos in tests, as they might not be available
on all platforms

[libc] Template the writing mode for the writer class ( #111559 )
...
Summary:
Currently we dispatch the writing mode off of a runtime enum passed in
by the constructor. This causes very unfortunate codegen for the GPU
targets where we get worst-case codegen because of the unused function
pointer for `sprintf`. Instead, this patch moves all of this to a
template so it can be masked out. This results in no dynamic stack and
uses 60 VGPRs instead of 117. It also compiles about 5x as fast.
