* lto.c (lto_read_variable_formal_parameter_constant_DIE): Don't
the type is a constant type. Set the assembler name and inform
the rest of the compiler about the new decl if the decl is not
(lto_read_subroutine_type_subprogram_DIE): Don't check for equivalency
of DECL_ASSEMBLER_NAME when determining if we have a builtin. Don't
try to read in function bodies for functions that already have bodies.

(lto_symtab_merge_decl): Don't merge decls that aren't TREE_PUBLIC.
Check for whether we matched a builtin function type before calling
lto_same_type_p on the generated type. Permit cases where the
declaration of an array is unbounded, but the definition is bounded.
Don't combine TREE_PUBLIC flags. Copy over DECL_SIZE and
DECL_SIZE_UNIT if necessary.
