qemu-arm: Enable software floating point support, and float tests. This helps to test floating point code on Cortex-M hardware. As part of this patch the link-time-optimisation was disabled because it wasn't compatible with software FP support. In particular, the linker could not find the __aeabi_f2d, __aeabi_d2f etc functions even though they were provided by lib/libm/math.c.

cortex-m3-qemu: refactor the port. Switch from CodeSourcery to ARM GCC and clean-up some stale files, also copy `main.c` and `mpconfigport.h` from bare-arm.

## With CoudeSourcery it's actually a little different, you just need `-T generic-m-hosted.ld`.
## Although for some reason `$(LD)` will not find that linker script, it works with `$(CC)`.
## It turns out that this is specific to CoudeSourcery, and ARM version of GCC ships something
## else instead and according to the following files, this is what we need to pass to `$(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.

py/modbuiltins: For round() builtin use nearbyint instead of round. The C nearbyint function has exactly the semantics that Python's round() requires, whereas C's round() requires extra steps to handle rounding of numbers half way between integers. So using nearbyint reduces code size and potentially eliminates any source of errors in the handling of half-way numbers. Also, bare-metal implementations of nearbyint can be more efficient than round, so further code size is saved (and efficiency improved). nearbyint is provided in the C99 standard so it should be available on all supported platforms.
