/* Each of these error-handling macros determines if TEST_EXPR holds.
If TEXT_EXPR fails to hold we return from the enclosing function and
print an error, either via adding an error on the given context CTXT
if CTXT is non-NULL, falling back to simply printing to stderr if CTXT
is NULL.
They have to be macros since they inject their "return" into the
function they are placed in.
The variant macros express:
(A) whether or not we need to return a value:
RETURN_VAL_IF_FAIL* vs
RETURN_IF_FAIL*,
with the former returning RETURN_EXPR, and
RETURN_NULL_IF_FAIL*
for the common case where a NULL value is to be returned on
error, and
(B) whether the error message is to be directly printed:
RETURN_*IF_FAIL
or is a format string with some number of arguments:
RETURN_*IF_FAIL_PRINTF*
They all use JIT_BEGIN_STMT/JIT_END_STMT so they can be written with
trailing semicolons.
