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.

Later patches turn the number of vector units into a poly_int.
We deliberately don't support applying GEN_INT to those (except
in target code that doesn't distinguish between poly_ints and normal

A recent change to remove the movdi_vfp_cortexa8 meant that ldrd was used in
ITs block even when arm_restrict_it was enabled.  Rather than just fixing this
latent issue, change the default of predicable_short_it to "no" so that only
16-bit instructions need to be marked with it.  As a result there are far fewer
patterns that need the attribute, and omitting predicable_short_it is no longer
causing issues.

	improve documentation, remove uses that are identical to the default.

	PR target/82748
	* config/rs6000/rs6000-builtin.def (BU_FLOAT128_1): Delete
	float128 helper macros, which are no longer used after deleting
	the old 'q' built-in functions, and moving the round to odd
	built-in functions to being special built-in functions.
	(BU_FLOAT128_2): Likewise.
	(BU_FLOAT128_1_HW): Likewise.
	(BU_FLOAT128_2_HW): Likewise.
	(BU_FLOAT128_3_HW): Likewise.
	(FABSQ): Delete old 'q' built-in functions.
	(COPYSIGNQ): Likewise.
	(SQRTF128_ODD): Move round to odd built-in functions to be
	special built-in functions, so that we can handle
	-mabi=ieeelongdouble.
	(TRUNCF128_ODD): Likewise.
	(ADDF128_ODD): Likewise.
	(SUBF128_ODD): Likewise.
	(MULF128_ODD): Likewise.

	(FMAF128_ODD): Likewise.
	* config/rs6000/rs6000-c.c (rs6000_cpu_cpp_builtins): Map old 'q'
	built-in names to 'f128'.
	* config/rs6000/rs6000.c (rs6000_fold_builtin): Remove folding the
	old 'q' built-in functions, as the machine independent code for
	'f128' built-in functions handles this.
	(rs6000_expand_builtin): Add expansion for float128 round to odd
	functions, keying off on -mabi=ieeelongdouble of whether to use
	the KFmode or TFmode variant.
	(rs6000_init_builtins): Initialize the _Float128 round to odd
	built-in functions.
	* doc/extend.texi (PowerPC Built-in Functions): Document the old
	_Float128 'q' built-in functions are now mapped into the new
	'f128' built-in functions.
