PR ada/61954
* gcc-interface/gigi.h (enum standard_datatypes): Add ADT_realloc_decl
(realloc_decl): New macro.
* gcc-interface/decl.c (gnat_to_gnu_entity) <E_Variable>: Use local
variable for the entity type and translate it as void pointer if the
entity has convention C.
(gnat_to_gnu_entity) <E_Function>: If this is not a definition and the
external name matches that of malloc_decl or realloc_decl, return the
correspoding node directly.
(gnat_to_gnu_subprog_type): Likewise for parameter and return types.
* gcc-interface/trans.c (gigi): Initialize void_list_node here, not...
Initialize realloc_decl.
* gcc-interface/utils.c (install_builtin_elementary_types): ...here.
(build_void_list_node): Delete.
* gcc-interface/utils2.c (known_alignment) <CALL_EXPR>: Return the
alignment of the system allocator for malloc_decl and realloc_decl.
Do not take alignment from void pointer types either.
