[PATCH 1/2, c-family]: Add 'z' to asm_fprintf_char_table

[Uros Bizjak]

Hello!

This patch is the prerequisite for my next patch. It enables %z
extension for asm_fprintf that will emit 'q' or 'l' suffixes for
instructions with word-sized operands.

2017-07-26  Uros Bizjak  <ubiz...@gmail.com>

    * c-format.c (asm_fprintf_char_table): Add 'z' to format_chars.

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

OK for mainline?

Uros.
