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.
