Alessandro Gatti c1c73d966e tests/run-tests.py: Unconditionally enable native tests if asked. 
This commit lets the test runner enumerate and run native tests if the
feature check fails but native tests were explicitly requested from the
command line.

The old behaviour would disable native tests anyway if the feature check
failed, however this hid a bug in the x86 native emitter that would be
triggered even during the feature check.  That meant the test suite
would pass on x86 even with a broken emitter, as those tests would have
been skipped anyway.

Now, if the user asks for native code it will get native code out of the
runner no matter what.

description="""Run and manage tests for MicroPython.
By default the tests are run against the unix port of MicroPython. To run it
against something else, use the -t option. See below for details.
Tests are discovered by scanning test directories for .py files or using the
specified test files. If test files nor directories are specified, the script
expects to be ran in the tests directory (where this file is located) and the
builtin tests suitable for the target platform are ran.
When running tests, run-tests.py compares the MicroPython output of the test with the output
produced by running the test through CPython unless a <test>.exp file is found, in which
case it is used as comparison.
If a test fails, run-tests.py produces a pair of <test>.out and <test>.exp files in the result
directory with the MicroPython output and the expectations, respectively.
""",
epilog="""\
The -t option accepts the following for the test instance:
- unix - use the unix port of MicroPython, specified by the MICROPY_MICROPYTHON
environment variable (which defaults to the standard variant of either the unix
or windows ports, depending on the host platform)
- webassembly - use the webassembly port of MicroPython, specified by the
MICROPY_MICROPYTHON_MJS environment variable (which defaults to the standard
variant of the webassembly port)
- port:<device> - connect to and use the given serial port device
- a<n> - connect to and use /dev/ttyACM<n>
- u<n> - connect to and use /dev/ttyUSB<n>
- c<n> - connect to and use COM<n>
- exec:<command> - execute a command and attach to its stdin/stdout
- execpty:<command> - execute a command and attach to the printed /dev/pts/<n> device
- <a>.<b>.<c>.<d> - connect to the given IPv4 address
- anything else specifies a serial port
Options -i and -e can be multiple and processed in the order given. Regex
"search" (vs "match") operation is used. An action (include/exclude) of
the last matching regex is used:
run-tests.py -i async - exclude all, then include tests containing "async" anywhere
run-tests.py -e '/big.+int' - include all, then exclude by regex
run-tests.py -e async -i async_foo - include all, exclude async, yet still include async_foo
