    This is a start of implementing type aliases (`type T1 = T2`) in the
    Go frontend.  This is incomplete, in that the reflection information
    is not updated for an embedded type alias.  It is also not well
    tested.  Finally, the change to the language has not been approved.
    This should be regarded as preliminary work for experimental use.

In order to handle large character lengths on (L)LP64 targets, switch
the GFortran character length from an int to a size_t.

This is an ABI change, as procedures with character arguments take
hidden arguments with the character length.

I also changed the _size member in vtables from int to size_t, as
there were some cases where character lengths and sizes were
apparently mixed up and caused regressions otherwise. Although I
haven't tested, this might enable very large derived types as well.

Also, as there are some places in the frontend were negative character
lengths are used as special flag values, in the frontend the character
length is handled as a signed variable of the same size as a size_t,
although in the runtime library it really is size_t.

I haven't changed the character length variables for the co-array
intrinsics, as this is something that may need to be synchronized with
OpenCoarrays.

This is v4 of the patch. v3 was applied but had to reverted due to
breaking bootstrap. The fix is in resolve.c:resolve_charlen, where
it's necessary to check that an expression is constant before using
mpz_sgn.

Overview of v3 of the patch: All the issues pointed out by FX's review
of v2 have been fixed. In particular, there are now new functions
gfc_mpz_get_hwi and gfc_mpz_set_hwi, similar to the GMP functions
mpz_get_si and mpz_set_si, except that they get/set a HOST_WIDE_INT
instead of a long value. Similarly, gfc_get_int_expr now takes a
HOST_WIDE_INT instead of a long, gfc_extract_long is replaced by
gfc_extract_hwi. Also, the preliminary work to handle
gfc_charlen_type_node being unsigned has been removed.

Regtested on x86_64-pc-linux-gnu and i686-pc-linux-gnu.

A big source of cache misses when compiling a recent version of
gimple-match.ii was the call to cv_cache.empty () in clear_cv_cache.
The problem was that at one early point the hash table had grown
to 8191 entries (128k on LP64 hosts).  It then stayed at that size
for the rest of the compilation, even though subsequent uses needed
only a small number of entries (usually fewer than ten).  We would
still clear the whole 128k each time clear_cv_cache was called.

empty() already looks for cases where the hash table is very big
and cuts it down.  At the moment it fires when the table is 1M
in size and reduces it to the next selected prime above 1K (so
almost 2K in practice).  One fix would have been to lower the
threshold, but that didn't feel like the right approach.  Reducing
the current limit of 1M by a factor of 8 would be pretty significant
on its own, but I think this cv_cache behaviour would have been a
problem even with 64k or 32k tables.

I think the existing check is really for cases in which even a
well-populated table would need to be shrunk rather than cleared.
Here the problem isn't that the table is excessively big in
absolute terms, more that one outlier has made the table much
too big for the general case.

traverse() already shrinks the table if it's "too empty",
which is taken to be if:

      no. elements * 8 < capacity && capacity > 32

So an alternative would be to apply the same test (and the same choice
of shrunken size) to empty_slow too.  The patch below does this.
It gives a 2.5% improvement in gimple-match.ii compile time at -O0 -g
and doesn't seem to adversely affect any other tests I've tried.

Of course, there's a theoretical risk of a table alternating between
one large element count and one small element count.  If there was a
factor of eight difference between the two, we could shrink the table
on seeing each small element count, then grow it again when adding the
large number of elements.  That seems pretty unlikely in practice
though.

Also, empty_slow() does involve a traversal if some form of manual
gc is needed on active elements, so trying to recover from an outlier
should have even more benefit there.  (cv_cache uses automatic gc and so
the traversal gets optimised away.)

The calculation of the existing 1M threshold was assuming that each
entry was pointer-sized.  This patch makes it use the actual size of the
entry instead.

Tested on aarch64-linux-gnu and x86_64-linux-gnu.

record_reg_classes is often the hottest function when generating
unoptimised output.  It seems typical for over 60% of the instructions
it handles to be moves, and of course moves tend to be the instructions
with the longest constraint strings.

Maybe we should avoid using move constraints to set costs in unoptimised
output and instead use the "natural" class for the mode being moved.
That's too invasive for stage 3 though.

However, seeing so many moves means that we see many "failing"
alternatives, usually because of '*' or because of hard registers
in function call sequences.  The frequency of alternatives that are
detected as failures after the first operand tends again to be more
than 60%.  Previously we would continue to process the other operands
of the alternative regardless.  This patch instead adds a short-cut.

As well as avoiding unnecessary work, it means that the alt_fail
variable can be jump-threaded away.

Tested on aach64-linux-gnu and x86_64-linux-gnu.  It reduces compile
time by about 1% on some tests with "-g -O0".
