Nevine Ebeid	fa3fbda07b	P-256 assembly optimisations for Aarch64. The ARMv8 assembly code in this commit is mostly taken from OpenSSL's `ecp_nistz256-armv8.pl` at `19e277dd19/crypto/ec/asm/ecp_nistz256-armv8.pl` (see Note 1), adapting it to the implementation in p256-x86_64.c. Most of the assembly functions found in `crypto/fipsmodule/ec/asm/p256-x86_64-asm.pl` required to support that code have their analogous functions in the imported OpenSSL ARMv8 Perl assembly implementation with the exception of the functions: - ecp_nistz256_select_w5 - ecp_nistz256_select_w7 An implementation for these functions was added. Summary of modifications to the imported code: * Renamed to `p256-armv8-asm.pl` * Modified the location of `arm-xlate.pl` and `arm_arch.h` * Replaced the `scatter-gather subroutines` with `select subroutines`. The `select subroutines` are implemented for ARMv8 similarly to their x86_64 counterparts, `ecp_nistz256_select_w5` and `ecp_nistz256_select_w7`. * `ecp_nistz256_add` is removed because it was conflicting during the static build with the function of the same name in p256-nistz.c. The latter calls another assembly function, `ecp_nistz256_point_add`. * `__ecp_nistz256_add` renamed to `__ecp_nistz256_add_to` to avoid the conflict with the function `ecp_nistz256_add` during the static build. * l. 924 `add sp,sp,#256` the calculation of the constant, 32(12-4), is not left for the assembler to perform.

P-256 assembly optimisations for Aarch64.

The ARMv8 assembly code in this commit is mostly taken from OpenSSL's `ecp_nistz256-armv8.pl` at 19e277dd19/crypto/ec/asm/ecp_nistz256-armv8.pl (see Note 1), adapting it to the implementation in p256-x86_64.c.

- ecp_nistz256_select_w5
- ecp_nistz256_select_w7
An implementation for these functions was added.

Summary of modifications to the imported code:
* Renamed to `p256-armv8-asm.pl`
* Modified the location of `arm-xlate.pl` and `arm_arch.h`
* Replaced the `scatter-gather subroutines` with `select subroutines`. The `select subroutines` are implemented for ARMv8 similarly to their x86_64 counterparts, `ecp_nistz256_select_w5` and `ecp_nistz256_select_w7`.
* `ecp_nistz256_add` is removed because it was conflicting during the static build with the function of the same name in p256-nistz.c. The latter calls another assembly function, `ecp_nistz256_point_add`.
* `__ecp_nistz256_add` renamed to `__ecp_nistz256_add_to` to avoid the conflict with the function `ecp_nistz256_add` during the static build.
* l. 924 `add	sp,sp,#256` the calculation of the constant, 32*(12-4), is not left for the assembler to perform.

Other modifications:
* `beeu_mod_inverse_vartime()` was implemented for AArch64 in `p256_beeu-armv8-asm.pl` similarly to its implementation in `p256_beeu-x86_64-asm.pl`.
* The files containing `p256-x86_64` in their name were renamed to, `p256-nistz` since the functions and tests defined in them are hereby running on ARMv8 as well, if enabled.
* Updated `delocate.go` and `delocate.peg` to handle the offset calculation in the assembly instructions.
* Regenerated `delocate.peg.go`.

Align with upstream on 'close STDOUT' lines.

When upstreaming c1d8c5b0e0 as
https://github.com/openssl/openssl/pull/10883 and then
https://github.com/openssl/openssl/pull/10930, we ended up diverging
slightly: in the upstream version, I ended up applying the same change
to the xlate files. Upstream also suggested "error closing STDOUT: $!".

Apply the same changes here.
