[gomp4.1] Add support for non-static data member iterators

Hi! As private/lastprivate/linear clauses now allow non-static data members in C++, it (unfortunately) means that also the iterator variables of distribute/for/simd/taskloop loops can be non-static data members. This patch implements it; tested on x86_64-linux, committed to gomp-4_1-branch.

[PATCH] Fix PR c++/30044

Here is a more modest approach to fixing this PR. Instead of updating current_template_parms with each newly processed template parameter, this patch just updates it with a dummy parameter level once per parameter list. So now in tsubst(), to fix the reported ICE we just have to avoid

[PATCH 1/4][PR target/65697][5.1] Backport stronger barriers for GCC,__sync builtins on Aarch64

Hello, The __sync builtins are implemented using barriers that are too weak for ARMv8 targets, this has been fixed on trunk for Aarch64. Since GCC-5.1 is also generating the incorrect code, it should also be fixed. The fix on trunk involved changes to the way that memory orders represent

Do they lack the CASA instruction with supervisor-mode ASI? What happens when the CASA instruction with user-mode ASI is executed in supervisor mode? For all LEON3 (with CASA support) the CASA instruction works in supervisor-mode regardless of ASI used. In user-mode CASA only works with
