9607f5ccf2 Fix handling of the "0:" label in arm-xlate.pl
When $label == "0", $label is not truthy, so `if ($label)` thinks there isn't
a label. Correct this by looking at the result of the s/// command.

Verified that there are no changes in the .S files created during a normal
build, and that the "0:" labels appear in the translation given in the error
report (and they are the only difference in the before and after output).

Fixes #21647

a97ca33f83 Restrict the Arm 'LDR REG, =VALUE' pseudo instruction on Neon, to appease clang
Unlike gcc, the clang assembler has issues with the maximum value of the literal
in the `ldr REG, #VALUE` pseudo-instruction (where the assembler places the
value into a literal pool and generates a PC-relative load from that pool) when
used with Neon registers.

Specifically, while dN refers to 64-bit Neon registers, and qN refers to 128-bit
Neon registers, clang assembly only supports a maximum of 32-bit loads to
either with this instruction.

Therefore restrict accordingly to avoid breakage when building with clang.

clang appears to support the correct maximums with the scalar registers xN etc.

This will prevent the kind of breakage we saw when #19914 was merged (which has
since been fixed by #20202) - assembly authors will need to manually apply the
literal load, as is done in #20202.

None of the Arm assembler code uses this pseudo-instruction anyway, as it
doesn't seem to avoid duplication of constants.

a21314dbbc Also check for errors in x86_64-xlate.pl.
In https://github.com/openssl/openssl/pull/10883, I'd meant to exclude
the perlasm drivers since they aren't opening pipes and do not
particularly need it, but I only noticed x86_64-xlate.pl, so
arm-xlate.pl and ppc-xlate.pl got the change.

That seems to have been fine, so be consistent and also apply the change
to x86_64-xlate.pl. Checking for errors is generally a good idea.

32be631ca1 Do not silently truncate files on perlasm errors
If one of the perlasm xlate drivers crashes, OpenSSL's build will
currently swallow the error and silently truncate the output to however
far the driver got. This will hopefully fail to build, but better to
check such things.

Handle this by checking for errors when closing STDOUT (which is a pipe
to the xlate driver).

db42bb440e ARM64 assembly pack: make it Windows-friendly.
"Windows friendliness" means a) unified PIC-ification, unified across
all platforms; b) unified commantary delimiter; c) explicit ldur/stur,
as Visual Studio assembler can't automatically encode ldr/str as
ldur/stur when needed.

3405db97e5 ARM assembly pack: make it Windows-friendly.
"Windows friendliness" means a) flipping .thumb and .text directives,
b) always generate Thumb-2 code when asked(*); c) Windows-specific
references to external OPENSSL_armcap_P.

(*) so far *some* modules were compiled as .code 32 even if Thumb-2
was targeted. It works at hardware level because processor can alternate
between the modes with no overhead. But clang --target=arm-windows's
builtin assembler just refuses to compile .code 32...
