selftest.h: add class line_table_test
input.c has a fixture class for running each selftest with a fresh
line_table, and logic for looping over various interesting line_table
test cases.
This patch exposes the above in selftest.h so that such
location-handling tests can be written in other files, renaming the
class from temp_line_table to line_table_test.
Also, the patch moves the stored line table ptr from being a member of
the test class to being a global GC-root, to avoid it being collected
if the GC runs during such a test.

DWARF: do not emit DW_TAG_variable to materialize DWARF procedures
Hello,
For -gdwarf-3 and newer, the DWARF back-end sometimes generates DWARF
procedures to factorize complex location descriptions. DWARF procedures
can be materialized as DW_TAG_dwarf_procedure DIEs, but actually any DIE
that can hold a DW_AT_location attribute is also accepted.
Unlike what I thought at some point, the DW_TAG_dwarf_procedure tag was
introduced in the DWARFv3 standard, not the DWARFv4 one, so the back-end
can always emit DW_TAG_dwarf_procedure DIEs, as this simplifies code and
prevents the types pruning pass from missing a DWARF procedure.
Boostrapped and regtested on x86_64-linux: no regression. Ok to commit?
Thank you in advance!

Evict selftest tempfiles from the diagnostics file cache
Selftests can use class selftest::temp_source_file to write out files
for testing input-handling, and the files are unlinked in the dtor.
This leads to stale entries in input.c's cache of file content, which
could lead to errors if a temporary filename gets reused during a run
of the selftests.
We don't normally expect files to be "deleted from under us", so
special-case this by adding a special way for temp_source_file's
dtor to purge any cache entries referring to it.

libgo: don't unset in shell script
Reportedly ksh fails to unset a variable that was not previously set.
Change match.sh and gotest to not unset LANG, but instead set LANG=C.
Also don't combine exporting and setting variable in a single statement.

crypto/aes, hash/crc32: ignore s390x specific files for now
These files are used to select s390x assembler support in the gc
toolchain. We don't currently have that support, as it is written in
the cmd/asm syntax rather than gas syntax. Mark the files to be ignored
for now, falling back to the default implementations.
