simplify_transformation_to_array had the nested loop unrolled 7 times,
which is reasonable given that it iterates over arrays of size
GFC_MAX_DIMENSIONS == 7.
The problem is that the last iteration increments the index, tests
that it's less than result->rank, and then accesses the arrays with
the incremented index.
We did not optimize out that part in the 7th iteration, so VRP flagged
the unreachable code as accessing arrays past the end.
It couldn't possibly know that we'd never reach that part, since the
test was on result->rank, and it's not obvious (for the compiler) that
result->rank <= GFC_MAX_DIMENSIONS.
Even an assert to that effect before the enclosing loop didn't avoid
the warning turned to error, though; I suppose there might be some
aliasing at play, because moving the assert into the loop does. An
assert on the index itself would also work, even more efficiently, but
we're just silencing the warning instead.

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 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.

Use the boolean_type_node setup by the middle-end instead of
redefining it. boolean_type_node is not used in GFortran for any
ABI-visible stuff, only internally as the type of boolean
expressions. There appears to be one exception to this, namely the
caf_get* and caf_send* calls which have boolean_type_node
arguments. However, on the library side they seem to use C _Bool, so I
suspect this might be a case of a argument mismatch that hasn't
affected anything so far.
The practical effect of this is that the size of such variables will
be the same as a C _Bool or C++ bool, that is, on most targets a
single byte. Previously we redefined boolean_type_node to be a Fortran
default logical kind sized variable, that is 4 or 8 bytes depending on
compile options. This might enable slightly more compact code, in case
the optimizer determines that the result of such a generated
comparison expression needs to be stored in some temporary location
rather than being used immediately.
