virtual_operand_p handled SSA names by looking at the flags of the
underlying variable.  This seems to be a relatively common source
of cache misses, mainly because virtual_operand_p is the first thing
tested by is_gimple_reg.

This patch caches the information in the SSA name itself.  Several
flags seem to be free so the patch arbitrarily uses public_flag.

Tested on aarch64-linux-gnu and x86_64-linux-gnu.  It improves
compile time by a small (<1%) but reproducable amount on the
tests I've tried.

	* tree-core.h (tree_base): Document the meaning of public_flag
	for SSA names.

    Change Struct_type::do_mangled_name to incorporate the field
    names even for hidden symbols. This is needed in cases where
    a package imports a type "S" that has an anonymous struct, e.g.
    
      // imported from some other package
      type S struct {
        X struct{ _ struct{} }
      }
    
    and then defines a local type that uses a structurally identical
    anonymous struct, e.g.
    
      // defined locally
      type T struct {
        U struct{ _ struct{} }
      }
    
    In the case above both types triggered the creation of hash/equal
    methods, but the method names were clashing (since both structs
    had the same mangled name).
