Remove __cplusplus >= 201103

Right now, we require a C++11 compiler, so the check is not needed any
longer.

gcc/analyzer/ChangeLog:

	* program-state.cc (program_state::operator=): Remove
	__cplusplus >= 201103.
	(program_state::program_state): Likewise.
	* program-state.h: Likewise.
	* region-model.h (class region_model): Remove dead code.

gcc/ChangeLog:

	* bitmap.h (class auto_bitmap): Remove
	__cplusplus >= 201103.
	* config/aarch64/aarch64.c: Likewise.
	* gimple-ssa-store-merging.c (store_immediate_info::store_immediate_info):
	Likewise.
	* sbitmap.h: Likewise.
