The 2nd and 3rd args of the ternary operator are treated like they are in
the same expression and must have similar types. void is not compatible
with int so that's why the compiler is complaining.
This patch moves the implementation of stream closure from a dedicated
method to the ioctl of the stream protocol, for each type that implements
closing. The benefits of this are:
1. Rounds out the stream ioctl function, which already includes flush,
seek and poll (among other things).
2. Makes calling mp_stream_close() on an object slightly more efficient
because it now no longer needs to lookup the close method and call it,
rather it just delegates straight to the ioctl function (if it exists).
3. Reduces code size and allows future types that implement the stream
protocol to be smaller because they don't need a dedicated close method.
Code size reduction is around 200 bytes smaller for x86 archs and around
30 bytes smaller for the bare-metal archs.
This caused a fatal compiler diagnostic after #750. This compiler
flag is already specified in the atmel-samd builds, so it makes
sense to do it here for the same reasons.

these are function prototypes not used in circuitpython. The
declarations began to conflict with ones in the upstream SDK
at some point, so delete them.
Recent vendor SDKs ship libs with code in .text section, which previously
was going into .irom0.text. Adjust the linker script to route these
sections back to iROM (follows upstream change).
The LHS passed to mp_obj_int_binary_op() will always be an integer, either
a small int or a big int, so the test for this type doesn't need to include
an "other, unsupported type" case.
The string "Q+?" is special in that it hashes to zero with the djb2
algorithm (among other strings), and a zero hash should be incremented to a
hash of 1.
Without the compiler enabled the mp_optimise_value is unused, and the
micropython.opt_level() function is not useful, so exclude these from the
build to save RAM and code size.
