Use the middle-end boolean_type_node
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.
Regression tested on x86_64-pc-linux-gnu.

moving the multiplication result into the final destination themselves

instruction patterns into insn_and_split patterns that now take the

compiler: fix off-by-1 array type len in Type::gc_symbol_constructor
Array type being built to hold GC var initializer was being created
with an extra/unneeded slot. Fix up the code to insure that the array
length matches the length of the initializer list.

compiler: call determine_types even for constant expressions
We need to call determine_types even for constant expressions, since a
constant expression may include code like unsafe.Sizeof(0). Something
needs to determine the type of the untyped 0, and that should be the
determine_types pass.
Implementing that triggered a compiler crash on test/const1.go because
it permitted some erroneous constants to make it all the way to the
backend. Catch that case by checking whether we get a constant
overflow error, and marking the expression invalid if we do. This is
a good change in any case, as previously we reported the same constant
overflow error multiple times, and now we only report it once.
Fixes GCC PR 78763.
