Subject: [PATCH] PR78465 Remove runtime tests for <atomic> macros
Authentication-results: sourceware.org; auth=none

Andrew MacLeod did some digging and foudn that this test was changed
from using #if to using a runtime if and abort() because the LOCK_FREE
macros resolved to runtime calls at one point. However, they later got
changed to predefined macros, and so can be changed back to using #if.

This should fix the regression on Solaris, where the mismatched
abort() declaration causes it to FAIL.

	PR libstdc++/78465
	* testsuite/29_atomics/headers/atomic/macros.cc: Replace runtime tests
	with preprocessor conditions.

Tested x86_64-linux, committed to trunk.
