[PATCH, i386]: Remove a couple of unneeded !TARGET_64BIT checks from va_arg handling functions

[Uros Bizjak]

These checks are already present in is_va_list_char_pointer.

    * config/i386/i386.c (ix86_va_start): Remove
    unneeded !TARGET_64BIT check.
    (ix86_gimplify_va_arg): Ditto.

Bootstrapped and regression tested on x86_64-linux-gnu {,-m32}.
