triggered with the RISC-V lp64 multilib in a GCC build configured with 
`--enable-multilib --enable-languages=all --target=riscv64-linux-gnu'. 
This is due to unconditional explicit use of F extension instructions 
within inline assembly, to access IEEE exception flags.  The use of 
these instructions is not allowed when building for a soft-float ABI.

Correct the problem by wrapping said inline assembly into a conditional 
such that if `D_SoftFloat' is true, then reads from IEEE exception flags 
return 0 and writes are ignored instead, complementing r270522 
("libphobos: Add D support for RISC-V Linux"), which is an updated 
version of <https://gcc.gnu.org/ml/gcc-patches/2019-04/msg00325.html>,

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.
