Subject: compiler.h: simplify data_race() macro
Date: Mon, 24 Jun 2024 18:39:49 +0300

-Wdeclaration-after-statement used since forever required statement
expressions to inject __kcsan_disable_current(), __kcsan_enable_current()
to mark data race. Now that it is gone, make macro expansion simpler.

__unqual_scalar_typeof() is wordy macro by itself.
"expr" is expanded twice.
