c++: micro-optimize most_specialized_partial_spec
This introduces an early exit test to most_specialized_partial_spec for
templates which have no partial specializations, saving some unnecessary
work during class template instantiation in the common case. In passing,
modernize the code a bit.
gcc/cp/ChangeLog:
* pt.cc (most_specialized_partial_spec): Exit early when
DECL_TEMPLATE_SPECIALIZATIONS is empty. Move local variable
declarations closer to their first use. Remove redundant
flag_concepts test. Remove redundant forward declaration.
