[PATCH v3 02/13] accel/tcg: Remove special case for GCC < 4.6

[marcandre.lureau@redhat.com]

From: Philippe Mathieu-Daudé <philmd@redhat.com>

Since commit efc6c070aca ("configure: Add a test for the
minimum compiler version") the minimum compiler version
required for GCC is 4.8.

We can safely remove the special case for GCC 4.6 introduced
in commit 0448f5f8b81 ("cpu-exec: Fix compiler warning
(-Werror=clobbered)").
No change for Clang as we don't know.
