Pirama Arumuga Nainar 6caa8da072 [profile] In Android, do not mkdir() dirs in GCOV_PREFIX 
Summary:
In Android, attempting to mkdir() or even stat() top-level directories
like /data causes noisy selinux denials.  During whole-system coverage
instrumentation, this causes a deluge of noisy messages that drown out
legitimate selinux denials, that should be audited and fixed.

To avoid this, skip creating any directory in GCOV_PREFIX (thereby
assuming that it exists).

- Android platform ensures that the GCOV_PREFIX used in Android is
created and read/writable by all processes.
- This only affects the Android platform (by checking against
__ANDROID_API_FUTURE__) and for apps built with Clang coverage, the
runtime will still create any non-existent parent directories for the
coverage files.
