["Kamil Rytarowski" <kamil%netbsd.org@localhost>]

Module Name:    src
Committed By:   kamil
Date:           Sun Feb 24 21:14:43 UTC 2019

Modified Files:
        src/sys/sys: kcov.h
        src/tests/modules: t_kcov.c

Log Message:
Add KCOV_LOAD() and KCOV_STORE() - new helper macros

New macros prefer 64-bit atomic operations whenever accessible.

As a fallback they use volatile move operations that are not known
to have negative effect in KCOV even if interrupted in the middle of
operation.

Enable kcov_basic and kcov_thread tests on targets without
__HAVE_ATOMIC64_OPS.
