On Visium, the compiler sometimes emits a NOP to avoid a pipeline hazard.

Tested on visium-elf and x86_64-suse-linux, applied on the mainline.


2018-01-16  Eric Botcazou  <ebotcazou@adacore.com>

	* c-c++-common/patchable_function_entry-decl.c: Use 3 NOPs on Visium.
	* c-c++-common/patchable_function_entry-default.c: Use 4 NOPs on Visium.
	* c-c++-common/patchable_function_entry-definition.c: Use 2 NOPs on Visium.
