Description

Move AMD64 MS to SysV calling convention conversion to assembly side

* cipher/Makefile.am: Add 'asm-common-amd64.h'.
* cipher/asm-common-amd64.h: New.
* cipher/blowfish-amd64.S: Add ENTER_SYSV_FUNC_* and EXIT_SYSV_FUNC for
each global function from 'asm-common-amd64.h'.
* cipher/cast5-amd64.S: Ditto.
* cipher/des-amd64.S: Ditto.
* cipher/rijndael-amd64.S: Ditto.
* cipher/twofish-amd64.S: Ditto.
* cipher/arcfour-amd64.S: Ditto.
* cipher/blowfish.c [HAVE_COMPATIBLE_GCC_WIN64_PLATFORM_AS]
(call_sysv_fn): Remove.
* cipher/cast5.c [HAVE_COMPATIBLE_GCC_WIN64_PLATFORM_AS]
(call_sysv_fn): Remove.
* cipher/twofish.c [HAVE_COMPATIBLE_GCC_WIN64_PLATFORM_AS]
(call_sysv_fn, call_sysv_fn5, call_sysv_fn6): Remove.
* cipher/rijndael.c (do_encrypt, do_decrypt)
[HAVE_COMPATIBLE_GCC_WIN64_PLATFORM_AS]: Remove assembly block for
calling SysV ABI function.
* cipher/arcfour.c [USE_AMD64_ASM] (encrypt_stream): Ditto.

Old approach was to convert MS ABI to SysV ABI calling convention
for AMD64 assembly functions at caller side. This patch moves
calling convention conversion to assembly/callee side.
