ports: Enable error text compression for various ports, but not all. Enabled on: bare-arm, minimal, unix coverage/dev/minimal, stm32, esp32, esp8266, cc3200, teensy, qemu-arm, nrf.

extmod/extmod.mk: Separate out extmod file list from py.mk to extmod.mk. This separates extmod source files from `py.mk`. Previously, `py.mk` assumed that every consumer of the py/ directory also wanted to include extmod/. However, this is not the case. For example, building mpy-cross uses py/ but doesn't need extmod/. This commit moves all extmod-specific items from `py.mk` to `extmod.mk` and explicitly includes `extmod.mk` in ports that use it. Signed-off-by: David Lechner <david@pybricks.com>

shared/runtime/gchelper: Drop cpu directive from ARM asm helpers. This drops the `.cpu` directive from the ARM gchelper_*.s files.

The exact CPU doesn't actually matter, but rather the supported assembly instruction set. So the files are renamed to *_thumb1.s and *thumb2.s to indicate the instruction set support instead of the CPU support. Signed-off-by: David Lechner <david@pybricks.com>

As part of this patch the link-time-optimisation was disabled because it wasn't compatible with software FP support.

## Although for some reason `$(LD)` will not find that linker script, it works with `$(CC)`.

qemu-arm: fully integrated test suite. This is primarily intended to provide testing of Thumb-specific code within Travis CI as well as if anyone else want to run it locally. As discussed in purposes. This is currently agains an emulated Cortex-M3 core, however in the near future it can extended to support M0, M0+ as well M4 (work in progress exists in sushihangover/qemu). It's probably true that most of the code base can be covered running uPy natively on a POSIX system, however we do have the tiny bit of assembly code. There may exist bugs related to endianness and type aliases, let alone potential standard library or compiler bugs or even architecture-specific optimisations. This could also incorporate lwIP (or other TCP/IP stack) integration as well as SDIO+FATFS drivers. The solution to inline the test cases was chose due to simplicity. It could alternatively be implemented in a number of different way (see #515), but this looked the simplest. Inclusion of tinytest was just to avoid writing boilerplate code for counting failed tests and other utility functions. Currently only a few functions are used, however this could be extended. Checking in the code instead of using submodule was a personal preference, but if people do want the pain of submodules, this can provided. This particular framework is also pretty good if one desires to run unit test on target. The approach with scripts being inlined is probably not quite suited for the size of memory an MCU has, but the tinytest itself should be good, if lower-level C code is to be unit tested.
