Richard Sandiford e047844bd6 Claw back some of the code size regression in 548.exchange2_r
This patch tries harder to detect cases in which the inner dimension
of an array access is invariant, such as:

     x(i, :) = 100

It fixes some of the code size regression in 548.exchange2_r, with
size improving by 5% compared to before the patch.  Of the two other
SPEC 2017 tests affected by loop versioning, 554.roms_r improved by a
trivial amount (0.3%) and 549.fotonik3d_r didn't change.  All three
results are with -Ofast -flto.

Jonathan Wakely fb54aa5915 PR libstdc++/88782 avoid ODR problems in std::make_shared
The old version of _Sp_counted_ptr_inplace::_M_get_deleter (up to GCC
8.2.0) expects to be passed a real std::typeinfo object, so mixing that
with the new definition of the __shared_ptr constructor (which always
passes the fake tag) leads to accessing the fake object as a real
std::typeinfo. Instead of trying to make it safe to mix the old and new
definitions, just stop using that function. By passing a reference to
__shared_ptr::_M_ptr to the __shared_count constructor it can be set
directly, without needing to obtain the pointer via the _M_get_deleter
back-channel. This avoids a virtual dispatch (which fixes PR 87514).

This means that code built against new libstdc++ headers doesn't use
_M_get_deleter at all, and so make_shared works the same whether RTTI is
enabled or not.

Also change _M_get_deleter so that it checks for a real type_info object
even when RTTI is disabled, by calling a library function. Unless
libstdc++ itself is built without RTTI that library function will be
able to test if it's the right type_info. This means the new definition
of _M_get_deleter can handle both the fake type_info tag and a real
type_info object, even if built without RTTI.

If linking to objects built against older versions of libstdc++ then if
all objects use -frtti or all use -fno-rtti, then the caller of
_M_get_deleter and the definition of _M_get_deleter will be consistent
and it will work. If mixing -frtti with -fno-rtti it can still fail if
the linker picks an old definition of _M_get_deleter and an old
__shared_ptr constructor that are incompatible. In that some or all
objects might need to be recompiled.

My patch for 64372 removed a bogus lvalue-rvalue conversion for one arm of a

Jason Merrill f18aa3a407 PR c++/86740, ICE with constexpr if and nested generic lambdas.
When we partially instantiate the constexpr if, we walk through its body to
see what it uses from the enclosing local_specializations.  That walk was
overlooking the use of 'count' in the captures of the innermost lambda,
because we weren't walking into the capture list.
