[patch,avr]: Minor fixes to some built-in macros

[Georg-Johann Lay <avr@gjlay.de>]

This patch does:

1) With 8-bit int, __INT24_MAX__ and __UINT24_MAX__ need a long long suffix.

2) Defines like __FLASH that indicate if address space is available should
   be like a predicate, i.e. 1 if the space is available.

Obvious and lightly tested.

Ok?

Johann


	* config/avr/avr-c.c (avr_cpu_cpp_builtins): Define __FLASH
	etc. to 1 and not to __flash.
	Use LL suffix for __INT24_MAX__ with -mint8.
	Use ULL suffix for __UINT24_MAX__ with -mint8.
