[PATCH x86 for review II] [8/39] x86_64: Remove fastcall references in x86_64 code

[Andi Kleen <ak@suse.de>]

From: Glauber de Oliveira Costa <gcosta@redhat.com>

Unlike x86, x86_64 already passes arguments in registers.  The use of
regparm attribute makes no difference in produced code, and the use of
fastcall just bloats the code.
