hash-common: avoid integer division to reduce call overhead
* cipher/hash-common.h (gcry_md_block_ctx): Replace 'blocksize' with
'blocksize_shift'.
* cipher/hash-common.c (_gcry_md_block_write): Use bit-level operations
instead of division to get number of blocks.
* cipher/gostr2411-94.c (gost3411_init): Initialize 'blocksize_shift'
instead of 'blocksize'.
* cipher/md2.c (md2_init): Ditto.
* cipher/md4.c (md4_init): Ditto.
