rtlanal: dead_or_set_regno_p should handle CLOBBER (PR83424)

In PR83424 combine's move_deaths puts a REG_DEAD note in the wrong place

Fix PR78588 - rtlanal.c:5210:38: runtime error: shift exponent 4294967295 is too large for 64-bit type
...
Building gcc with -fsanitize=undefined shows:
rtlanal.c:5210:38: runtime error: shift exponent 4294967295 is too large for 64-bit type 'long unsigned int'
This happens because if_then_else_cond() in combine.c calls
num_sign_bit_copies() in rtlanal.c with mode==BLKmode.
5205 bitwidth = GET_MODE_PRECISION (mode);
5206 if (bitwidth > HOST_BITS_PER_WIDE_INT)
5207 return 1;
5208
5209 nonzero = nonzero_bits (x, mode);
5210 return nonzero & (HOST_WIDE_INT_1U << (bitwidth - 1))
5211 ? 1 : bitwidth - floor_log2 (nonzero) - 1;
This causes (bitwidth - 1) to wrap around.

Rework the main handling so that it operates on independently-

to check lowpart offsets, without trying to find an equivalent
integer mode first. Handle WORDS_BIG_ENDIAN != REG_WORDS_BIG_ENDIAN

Fix handling of unknown sizes in rtx_addr_can_trap_p
...
If the size passed in to rtx_addr_can_trap_p was zero, the frame
handling would get the size from the mode instead. However, this
too can be zero if the mode is BLKmode, i.e. if we have a BLKmode
memory reference with no MEM_SIZE (which should be rare these days).
This meant that the conditions for a 4-byte access at offset X were
stricter than those for an access of unknown size at offset X.
This patch checks whether the size is still zero, as the
SYMBOL_REF handling does.

Add a load_extend_op wrapper
...
LOAD_EXTEND_OP only applies to scalar integer modes that are narrower
than a word. However, callers weren't consistent about which of these
checks they made beforehand, and also weren't consistent about whether
"smaller" was based on (bit)size or precision (IMO it's the latter).
This patch adds a wrapper to try to make the macro easier to use.
LOAD_EXTEND_OP is often used to disable transformations that aren't
beneficial when extends from memory are free, so being stricter about
the check accidentally exposed more optimisation opportunities.
"SUBREG_BYTE (...) == 0" and subreg_lowpart_p are implied by
paradoxical_subreg_p, so the patch also removes some redundant tests.
The patch doesn't change reload, since different checks could have
unforeseen consequences.

Move misplaced assignment in num_sign_bit_copies1
...
The old assignment to bitwidth was before we handled VOIDmode with:
if (mode == VOIDmode)
mode = GET_MODE (x);
so when VOIDmode was specified we would always use:
if (bitwidth < GET_MODE_PRECISION (GET_MODE (x)))
{
num0 = cached_num_sign_bit_copies (x, GET_MODE (x),
known_x, known_mode, known_ret);
return MAX (1,
num0 - (int) (GET_MODE_PRECISION (GET_MODE (x)) - bitwidth));
}
For a zero bitwidth this always returns 1 (which is the most
pessimistic result).

While changing LABEL_REF_LABEL it might as well become an inline

because it is still possible to use XEXP and related macros on a

other unfortunate thing is that the generators actually create LABEL_REF

Remove REAL_VALUE_FROM_CONST_DOUBLE
...
To maintain symmetry after the previous removal of
CONST_DOUBLE_FROM_REAL_VALUE, this patch also gets rid of
REAL_VALUE_FROM_CONST_DOUBLE. All the macro did was copy the
contents of CONST_DOUBLE_REAL_VALUE into a temporary real_value
structure. In many cases there was no need for this temporary
and we could simply use the CONST_DOUBLE_REAL_VALUE directly.
For that reason this patch is less automatic than the others.
Bootstrapped & regression-tested on x86_64-linux-gnu. Also tested by
building one target per CPU directory and checking that there were
no new warnings and no changes in testsuite output at -O2.
