PR libstdc++/86138 prevent implicit instantiation of COW empty rep

The explicit instantiation declarations for std::basic_string are
disabled for C++17 (and later) so that basic_string symbols get
implicitly instantiated in every translation unit that needs them.  On
targets that don't support STB_GNU_UNIQUE this leads to multiple copies
of the empty rep symbol for COW strings. In order to detect whether a
COW string needs to deallocate its storage it compares the address with
the empty rep.  When there are multiple copies of the empty rep object
the address is not unique, and so string destructors try to delete the
empty rep, which crashes.

In order to guarantee uniqueness of the _S_empty_rep_storage symbol this
patch adds an explicit instantiation declaration for just that symbol.
This means the other symbols are still implicitly instantiated in C++17
code, but for the empty rep the definition in the library gets used.

Separately, there is no need for C++17 code to implicitly instantiate
the I/O functions for strings, so this also restores the explicit
instantiation declarations for those functions.

PR libstdc++/83328 add correct basic_string::insert for initializer_list

The SSO basic_string has a non-standard insert(iterator, initializer_list)
overload, from a C++0x draft. This adds the correct overload, while also
preserving the old one so that the old symbol is still exported from the

The COW basic_string doesn't have any of the C++11 changes to the insert
overloads (they all still have non-const iterator parameters and the
ones that should return an iterator still return void). This doesn't

In more detail, gdb fails to print the value of d:

16        ++v;
$1 = <optimized out>
$2 = 112
<optimized out> != 112
...

Variable d is a local variable in function foo, initialized from global array a.
When compiling, first cddce1 removes the initialization of d in foo, given
that d is not used afterwards.  Then ipa marks array a as write-only, and
removes the stores to array a in main.  This invalidates the location
expression for d, which points to a[i], so it is removed, which is why gdb
ends up printing <optimized out> for d.

array a from being marked as write-only.

[AArch64] Support for LDP/STP of Q-registers

This patch adds support for generating LDPs and STPs of Q-registers.
This allows for more compact code generation and makes better use of the ISA.

It's implemented in a straightforward way by allowing 16-byte modes in the
sched-fusion machinery and adding appropriate peepholes in aarch64-ldpstp.md
as well as the patterns themselves in aarch64-simd.md.

It adds a new no_ldp_stp_qregs tuning flag.
I use it to restrict the peepholes in aarch64-ldpstp.md from merging the
operations together into PARALLELs. I also use it to restrict the sched fusion
check that brings such loads and stores together. This is enough to avoid
forming the pairs when the tuning flag is set.

I didn't see any non-noise performance effect on SPEC2017 on Cortex-A72 and Cortex-A53.

[8/n] PR85694: Make patterns check for target support

This patch makes pattern recognisers do their own checking for vector
types and target support.  Previously some recognisers did this
themselves and some left it to vect_pattern_recog_1.

Doing this means we can get rid of the type_in argument, which was
ignored if the recogniser did its own checking.  It also means
we create fewer junk statements.

[7/n] PR85694: Add a vect_pattern_detected helper

This message is a long write-up for a patch that simply adds a common
routine for printing the "vector_foo_pattern: detected:" messages.

The reason for doing this is that some routines check for target support
themselves and some leave it to vect_pattern_recog_1.  Those that leave
it to vect_pattern_recog_1 currently print these "detected:" messages if
the statements have the right form, even if the pattern is eventually
discarded.  IMO that's useful, and a lot of existing scan tests rely on it.

However, a later patch makes patterns do their own testing, and stops
them creating pattern statements until the tests have passed.  This means
(a) they need to print the "detected:" message earlier and (b) the pattern
statement won't be around to print.

The patch therefore makes all routines print the original statement
rather than the pattern one.  That information isn't obvious otherwise,
whereas vect_pattern_recog_1 already prints the pattern statement
in the case of a successful match.  This also avoids the previous
situation in which a routine could print "detected:" and then
silently bail out before saying what had been detected.
