Antony Polukhin 174f9257a7 libstdc++: Optimize std::seed_seq construction 
When std::seed_seq is constructed from random access iterators we can
detect the internal vector size in O(1). Reserving memory for elements
in such cases may avoid multiple memory allocations.

Signed-off-by: Jonathan Wakely <jwakely@redhat.com>

libstdc++-v3/ChangeLog:

	* include/bits/random.tcc (seed_seq::seed_seq): Reserve capacity
	if distance is O(1).
	* testsuite/26_numerics/random/pr60037-neg.cc: Adjust dg-error
	line number.
