PR libstdc++/89130 restore support for non-MoveConstructible types
The changes to "relocate" std::vector elements can lead to new errors
outside the immediate context, because moving the elements to new
storage no longer makes use of the move-if-noexcept utilities. This
means that types with deleted moves no longer degenerate to copies, but
are just ill-formed. The errors happen while instantiating the
noexcept-specifier for __relocate_object_a, when deciding whether to try
to relocate.
This patch introduces indirections to avoid the ill-formed
instantiations of std::__relocate_object_a. In order to avoid using
if-constexpr prior to C++17 this is done by tag dispatching. After this
patch all uses of std::__relocate_a are guarded by checks that will
support sensible code (i.e. code not using custom allocators that fool
the new checks).

[PR87770] test partial specializations for type dependence
When instantiating a partial specialization of a template member
function for a full specialization of a class template, we test
whether the context of variables local to the partial specialization,
i.e., the partial specialization itself, is dependent, and this ICEs
in type_dependent_expression_p, when checking that the function type
isn't type-dependent because it is not in a type-dependent scope.
We shouldn't have got that far: the previous block in
type_dependent_expression_p catches cases in which the function itself
takes template arguments of its own, but it only did so for primary
templates, not for partial specializations. This patch fixes that.

I restricted output of inline PLT sequences to when TLS marker relocs
were also available, which is obviously true when just considering
assembler support. However, there is a -mno-tls-markers option to
disable emitting the marker relocs. Currently that option also
disables inline PLT sequences, which is a bug (*). This patch fixes
that problem.
*) To be honest, it was a deliberate bug. I didn't want to have to
deal with inline PLT __tls_get_addr sequences lacking the marker
relocs in the linker, but it turns out the existing linker support for
old-style __tls_get_addr calls works reasonably well.

Here, we capture nf, then the use of the proxy decays to a constant during

we walk through the lambda body to see which proxies are still used, but we
