When I refactored the filesystem_error code I changed it to only use the
constructor parameter in the what() string, instead of the string
returned by system_error::what(). That meant it no longer included the
description of the error_code that system_error adds. This restores the

libgo/testsuite: ignore symbols with a leading dot in symtogo
On AIX, a function has two symbols, a text symbol (with a leading dot)
and a data one (without it).
As the tests must be run only once, only the data symbol can be used to
retrieve the final go symbol. Therefore, all symbols beginning with a dot
are ignored by symtogo.

runtime: mark memequal and memclrNoHeapPointers nosplit
They are wrappers of libc functions that use no stack. Mark them
nosplit so the linker won't patch it to call __morestack_non_split.

[Darwin, testsuite] Fix isystem-2.c.
For the test to succeed there needs to be some header that is to be found in
the 'expected' place i.e. <sysroot>/usr/include/. It's important that it is
not the name of a header for which fixincludes have been applied, since such
headers will be found in the gcc include-fixed dir and, in general, reference
additional headers. The dummy sysroot will prevent the additional headers
from being found, resulting in a failed test. The fix is to use a header name
that isn't expected to be present in a real sysroot.
