This permits TestScript to work when gccgo is not installed.
Previous testing was using a previously installed gccgo, not the newly
built one.
This revealed that the testing of whether an internal package is
permitted was incorrect for standard library packages, since the
uninstalled gccgo can see internal packages in the uninstalled libgo.
Fix the internal package tests.
This permitted removing a couple of gccgo-specific changes in the
testsuite.

"r264537: Change EQ_ATTR_ALT to support up to 64 alternatives" changed
the format of EQ_ATTR_ALT from ii to ww. This broke the bootstrap on
32-bit systems, because the formula for rtx_code_size assumed that only
certain codes contain HOST_WIDE_INTs. This did not surface on 64-bit
systems, because rtunion is 8 bytes anyway, but on 32-bit systems it's
only 4 bytes. This resulted in out-of-bounds writes and memory
corruptions in genattrtab.

On S/390 there is a need to support more than 32 instruction
alternatives per define_insn. Currently this is not explicitly
prohibited or unsupported: MAX_RECOG_ALTERNATIVES is equal 35, and,
futhermore, the related code uses uint64_t for bitmaps in most places.
However, genattrtab contains the logic to convert (eq_attr "attribute"
"value") RTXs to (eq_attr_alt bitmap) RTXs, where bitmap contains
alternatives, whose "attribute" has the corresponding "value".
Unfortunately, bitmap is only 32 bits.
When adding the 33rd alternative, this led to (eq_attr "type" "larl")
becoming (eq_attr_alt -1050625 1), where -1050625 == 0xffeff7ff. The
cleared bits 12, 21 and 32 correspond to two existing and one newly
added insn of type "larl". compute_alternative_mask sign extended this
to 0xffffffffffeff7ff, which contained non-existent alternatives, and
this made simplify_test_exp fail with "invalid alternative specified".
I'm not sure why it didn't fail the same way before, since the top bit,
which led to sign extension, should have been set even with 32
alternatives. Maybe simplify_test_exp was not called for "type"
attribute for some reason?
This patch widens EQ_ATTR_ALT bitmap to 64 bits, making it possible to
gracefully handle up to 64 alternatives. It eliminates the problem with
the 33rd alternative on S/390.

S/390 epilogue ends with (parallel [(return) (use %r14)]) instead of
the more usual (return) or (simple_return). This sequence is not
recognized by the conditional return logic in try_optimize_cfg ().
This was introduced for processors older than z196, where it is
sometimes profitable to use call-clobbered register for returning
instead of %r14. On newer processors we always return via %r14,
for which the fact that it's used is already reflected by
EPILOGUE_USES. In this case a simple (return) suffices.
This patch changes return_use () to emit simple (return)s when
returning via %r14. The resulting sequences are recognized by the
conditional return logic in try_optimize_cfg ().
