[PATCH] D54739: [Sanitizer] intercept setvbuf on other platforms where it is supported

[Kamil Rytarowski via Phabricator via llvm-commits]

Please revert, I've not accepted the commit and it claims reviewed by me.

Then please add the interceptors and add test requested by @vitalybuka to read a single byte from buffers.
