testsuite: new require effective target indirect_calls
...
This patch adds a new dg_require_effective_target procedure to the
testsuite infrastructure: indirect_calls. This new function tells
whether a target supports calls to non-constant call targets.
This patch also annotates the tests in the gcc.c-torture testuite that
require support for indirect calls.

indirect_calls.

Force IFN_LOAD/STORE_LANES operands to be memory (PR91577)
...
This patch uses the workaround Richi suggested in the PR: make
discover_nonconstant_array_refs mark the source of an IFN_LOAD_LANES
call and the destination of an IFN_STORE_LANES call as addressable,
so that they don't end up being REG rtxes during expansion.
I had to move the discover_nonconstant_array_refs call outside the
currently_expanding_to_rtl block since otherwise mark_addressable
just queues the decision for later.

Remove broken URL from libstdc++ manual
...
The URL for the "What Are Allocators Good For?" article has been a
recurring source of problems. It moved from the C/C++ Users Journal
website to the Dr Dobbs site after CUJ shut down, and the original
domain changed hands, leaving old links pointing to nefarious sites.
Now the URL to the copy on drdobbs.com no longer works either and I
can't find a (legal) copy of the article online. The simplest solution
is to remove the URL.

Improve PRNG jumping when using threads
...
Currently, when a new thread needs to use the RANDOM_NUMBER intrinsic,
the per-thread PRNG state is initialized by copying the master state
and then jumping forwards N*2**128 entries in the stream so that the
PRNG streams for different threads don't alias each other, where N is
the number of threads that have so far initialized the PRNG.
With this patch the master state itself is jumped forwards once each
time a new thread initializes the PRNG, thus obviating the need to
jump through all the N-1 previous streams. Effectively turning an O(N)
algorithm into an O(1) one.
Regtested on x86_64-pc-linux-gnu.

2019-09-05 Janne Blomqvist <jb@gcc.gnu.org>
* intrinsics/random.c (master_init): Replace with
master_state.init.
(njumps): Remove variable.
