libphobos: Move rt.sections modules to gcc.sections
These modules depend on a mixture between how the compiler emits run-time module information, and what functions are exposed by the platform to inquire about loaded global and thread-local data sections. As the upstream implementation is written to work only with how the reference D compiler writes out data, much of what is present does not apply to the GCC D front-end. So it has been moved to a non-upstream location in the source tree, where most of it will be rewritten once each port has been completed. The only tested module sections/elf_shared.d has been cleaned up so that all deprecated declarations have been removed, as well as the brittle module collision checking, which required bss_sections.c. All other ports have been left unchanged apart from a commonizing of attributes. libphobos/ChangeLog: 2019-04-13 Iain Buclaw <ibuclaw@gdcproject.org> * libdruntime/Makefile.am (DRUNTIME_CSOURCES): Remove bss_sections.c.
