0eaee4abb1 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.

0e99e09339 PR fortran/91414: Improved PRNG
Update the PRNG from xorshift1024* to xoshiro256** by the same
author. For details see

http://prng.di.unimi.it/

and the paper at

https://arxiv.org/abs/1805.01407

Also the seeding is slightly improved, by reading only 8 bytes from
the operating system and using the simple splitmix64 PRNG to fill in
the rest of the PRNG state (as recommended by the xoshiro author),
instead of reading the entire state from the OS.

0aa6ee3670 Make GFORTRAN_9 symbol node depend on GFORTRAN_8.
At some point when the GFORTRAN_9 node was added it was forgotten to
make it depend on GFORTRAN_8. This patch fixes this.

Committed as obvious.
