[PowerPC64] Modify register defines in gcm-hash.asm

See merge request !10

* powerpc64/p7/chacha-2core.asm: New file.

* chacha-crypt.c (_chacha_crypt_2core, _chacha_crypt32_2core): New
variants of chacha_crypt, using _chacha_2core to do two blocks at
a time.
* chacha-internal.h (_chacha_2core, _chacha_2core32): Add declarations.
* configure.ac (asm_nettle_optional_list): Add chacha-2core.asm.

* ecc-mod-inv.c (ecc_mod_inv): Use passed in scratch for all
scratch needs, don't use memory after the result area.
* ecc-ecdsa-sign.c (ecc_ecdsa_sign): Update invert call.
* ecc-ecdsa-verify.c (ecc_ecdsa_verify): Likewise.
* ecc-eh-to-a.c (ecc_eh_to_a): Likewise.
* ecc-j-to-a.c (ecc_j_to_a): Likewise.
* ecc-gostdsa-verify.c (ecc_gostdsa_verify): Likewise.
* ecc-internal.h (ECC_MOD_INV_ITCH, ECC_J_TO_A_ITCH)
(ECC_EH_TO_A_ITCH): Update accordingly, but no change in total
scratch need.

* ecc-internal.h (ECC_J_TO_A_ITCH): Generalize, and take invert
itch as an argument, similarly to ECC_EH_TO_A_ITCH. Updated all
secp and gost curve definitions to use it.

* ecc-secp384r1.c (ecc_secp384r1_inv): New function, modular
inverse using powering.
(_nettle_secp_384r1): Analogous updates. Increases signing
performance roughly 15% on x86_64.

* ecc-secp224r1.c (ecc_secp224r1_inv): New function, modular
inverse using powering.
(_nettle_secp_224r1): Analogous updates. Increases signing
performance roughly 17% on x86_64.

* ecc-secp256r1.c (ecc_secp256r1_inv): New function, modular
inverse using powering.
(_nettle_secp_256r1): Analogous updates. Increases signing
performance roughly 6% on x86_64.

* ecc-secp521r1.c (ecc_secp521r1_inv): New function, modular
inverse using powering.
(_nettle_secp_521r1): Analogous updates. Increases signing
performance roughly 15% on x86_64.

* ecc-secp192r1.c (ecc_secp192r1_inv): New function, modular
inverse using powering.
(_nettle_secp_192r1): Use it for p.invert, and also update
h_to_a_itch. Increases signing performance roughly 25% on x86_64.
