PR c++/90047 - ICE with enable_if alias template.

In order to make alias templates useful for SFINAE we instantiate them under
the prevailing 'complain' argument, so an error encountered while
instantiating during SFINAE context is silent.  The problem in this PR comes
when we later look up the erroneous instantiation and don't give an error at
that point.  Fixed by not adding an erroneous instantiation to the hash
table, so we instantiate it again when needed and get the error.  This
required changes to a number of tests, which previously said "substitution
failed:" with no explanation of what the failure was; now we properly
explain.

7 days agolibphobos: Move rt.sections modules to gcc.sections
ibuclaw [Sat, 13 Apr 2019 15:29:15 +0000 (15:29 +0000)]
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.

2019-04-13  Iain Buclaw  <ibuclaw@gdcproject.org>
