Interestingly, this only became a problem when CL 32850 marked
TestImportMain as parallel. Before that, "x" was overwritten and remove
in a later test, TestGoBuildOutput. The latter test is not marked as
parallel, so now it is run first. It is rather fragile for two tests to
compete over the same filename, but this change is correct regardless.

This change buffers the entire profile and converts in one shot
in the profile writer, and could use more memory than necessary
to output protocol buffer formatted profiles. It should be
possible to convert each chunk in a stream (maybe maintaining
some minimal state to output in the end) which could save on

We add runtime/cgo to the list of import paths for various cases that
imply external linking mode, but before this change we did not add for
an explicit request of external linking mode. This fixes the case where
you are using a non-default buildmode that implies a different
compilation option (for example, -buildmode=pie implies -shared) and the
runtime/cgo package for that option is stale.
No test, as I'm not sure how to write one. It would require forcing a
stale runtime/cgo.

This change adds code, originally written by Russ Cox <rsc@golang.org>

This code reads the entire binary format for conversion to the

to incrementally read and convert segments of the binary format,
so that the entire profile does not need to be stored in memory.
This change also contains contributions by Daria Kolistratova
<daria.kolistratova@intel.com> from the rolled-back change
golang.org/cl/30556 adapting the code to be used by the package

Windows has a limit of 260 characters on normal paths, but it's possible
to use longer paths by using "extended-length paths" that begin with
`\\?\`. This commit attempts to transparently convert an absolute path
to an extended-length path, following the subtly different rules those
paths require. It does not attempt to handle relative paths, which
continue to be passed to the operating system unmodified.
This adds a new test, TestLongPath, to the os package. This test makes
sure that it is possible to write a path at least 400 characters long
and runs on every platform. It also tests symlinks and hardlinks, though
symlinks are not testable with our builder configuration.
