[PATCH v2 04/13] compiler.h: remove GCC < 3 __builtin_expect fallback

[marcandre . lureau]

From: Marc-André Lureau <marcandre.lureau@redhat.com>

Since commit efc6c07 ("configure: Add a test for the minimum compiler
version"), QEMU explicitely depends on GCC >= 4.8.

(clang >= 3.8 advertizes itself as GCC >= 4.2 compatible)
