Earlier GFortran used to redefine boolean_type_node, which in the rest
of the compiler means the C/C++ _Bool/bool type, to the Fortran
default logical type.  When this redefinition was removed, a few
issues surfaced. Namely,

1) PR 82869, where we created a boolean tmp variable, and passed it to
the runtime library as a Fortran logical variable of a different size.

2) Fortran specifies that logical operations should be done with the
default logical kind, not in any other kind.

3) Using 8-bit variables have some issues, such as
   - on x86, partial register stalls and length prefix changes.
   - s390 has a compare with immediate and jump instruction which
     works with 32-bit but not 8-bit quantities.

This patch addresses these issues by introducing a type
logical_type_node which is a Fortran LOGICAL variable of default
kind. It is then used in places were the Fortran standard mandates, as
well as for compiler generated temporary variables.

For x86-64, using the Polyhedron benchmark suite, no performance or
code size difference worth mentioning was observed.

Regtested on x86_64-pc-linux-gnu.

We currently generate (sometimes pretty long) sequences of integer
insns to implement the various cstore patterns.  If the CPU has a fast
isel, we can use that at the same latency as of just two integer insns
(you also get a load immediate of 1, and sometimes one of 0 as well,
but those are not in the critical path: they don't depend on any other
instruction).

There are a few patterns that already are implemented with just two
instructions; so don't use isel in that case (I still need to check
all lt/gt/ltu/gtu/le/leu/ge/geu patterns with all SI/DI combinations,
one or two might be better without isel).

This introduces a new GPR2 mode iterator, for those patterns that use
two independent integer modes.

Without this we aren't getting proper memcpy inlining on RISC-V systems,
which is particularly disastrous for Dhrystone performance on RV32IM
systems.

Use no suffix at all in the musl dynamic linker name for hard
float ABI. Use -sf and -sp suffixes in musl dynamic linker name
for soft float and single precision ABIs. The following table
outlines the musl interpreter names for the RISC-V ABI names.

musl interpreter        | RISC-V ABI
----------------------- | -------------
ld-musl-riscv32.so.1    | riscv32-ilp32d

Some of the shift expanders accepted nonmemory_operands but were only
able to handle register_operands or CONST_INTs.  This is probably
academic without SVE, since we're not likely to see shifts by other
types of constant (const_wide_ints, consts, etc).  But for SVE,
it's possible for a vectorised shift induction to have a CONST_POLY_INT
shift amount.

This patch makes the expanders use aarch64_reg_or_imm instead.

Canonicalize x / (- y) into (-x) / y.

This moves negates out of the RHS of a division in order to
allow further simplifications and potentially more reciprocal CSEs.

Currently the code A << (B - C) is not simplified.
However at least a more specific case of 1U << (C -x) where
C = precision(type) - 1 can be simplified to (1 << C) >> x.

This is done by adding a new simplification rule in match.pd.
