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).

two independent integer modes.

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.

FT32 makes use of multiple address spaces. When trying to inspect
objects in GDB, GDB was treating them as a straight "const". The cause
seems to be in GCC DWARF2 output.
This output is handled in gcc/gcc/dwarf2out.c, where modified_type_die()
checks that TYPE has qualifiers CV_QUALS. However while TYPE has
ADDR_SPACE qualifiers, the modified_type_die() explicitly discards the
ADDR_SPACE qualifiers.
This patch retains the ADDR_SPACE qualifiers as modified_type_die()
outputs the DWARF type tree. This allows the types to match, and correct
type information for the object is emitted.
