Subject: [Modules] Add stdatomic to the list of builtin headers
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=923cfd3d650cd21d32a37469a40d40e857529843;p=clang

[Modules] Add stdatomic to the list of builtin headers

Since it's provided by the compiler. This allows a system module map
file to declare a module for it.

No test change for cstd.m, since stdatomic.h doesn't function without a
relatively complete stdint.h and stddef.h, which tests using this module
don't provide.
