From now on, we always display the given object's type instead of just reporting "object".
Additionally, make the format of return type errors match the format of argument errors.
Closes GH-5625
To avoid duplicate type checks. In debug builds arginfo is still
checked and will generate an assertions if the function doesn't
subsequently throw an exception.
Some test results change due to differences in zpp and arginfo
error messages.
PHP requires integer typehints to be written "int" and does not
allow "integer" as an alias. This changes type error messages to
match the actual type name and avoids confusing messages like
"must be of the type integer, integer given".
