Unable to map ``"bool", "complex128"`` for ``CudaTarget``

Here's the MWE

```python
import loopy as lp
import numpy as np
knl = lp.make_kernel(
domains = "{ [_0]: 0<=_0<10 }",
instructions = "out[_0] = 2*a[_0]",
kernel_data = [lp.GlobalArg("out", shape=lp.auto, dtype="bool"),
lp.GlobalArg("a", shape=lp.auto, dtype="bool")],
target=lp.CudaTarget(),
lang_version=(2018, 2))
#knl = lp.make_kernel(
# domains = "{ [_0]: 0<=_0<10 }",
# instructions = "out[_0] = 2*a[_0]",
# kernel_data = [lp.GlobalArg("out", shape=lp.auto, dtype="complex128"),
# lp.GlobalArg("a", shape=lp.auto, dtype="complex128")],
# target=lp.CudaTarget(),
# lang_version=(2018, 2))
print(knl)
lp.generate_code_v2(knl).device_code()
```
Generated kernel

```console
---------------------------------------------------------------------------
KERNEL: loopy_kernel
---------------------------------------------------------------------------
ARGUMENTS:
out: type: np:dtype('bool'), shape: (10), dim_tags: (N0:stride:1) out aspace: global
a: type: np:dtype('bool'), shape: (10), dim_tags: (N0:stride:1) in aspace: global
---------------------------------------------------------------------------
DOMAINS:
{ [_0] : 0 <= _0 <= 9 }
---------------------------------------------------------------------------
INAME TAGS:
_0: None
---------------------------------------------------------------------------
INSTRUCTIONS:
for _0
out[_0] = 2*a[_0] {id=insn}
end _0

```
Here's the trace
