pca006132 4132c450a5 firmware: runtime changes for exception 
Ported from:
M-Labs/artiq-zynq#162

This includes new API for exception handling, some refactoring to avoid
code duplication for exception structures, and modified protocols to
send nested exceptions and avoid string allocation.

Sebastien Bourdeauducq 35d21c98d3 Revert "runtime: expose rint from libm" 
Consistency with NAR3/Zynq where rint is not available.

This reverts commit f5100702f6.

occheung 7542105f0f board_misoc: remove pcr 
VexRiscv seems to not support additional hardware performance counter, at least I have not seen any documentation on how to use it.

David Nadlinger d95e619567 compiler: Implement binary NumPy math functions (arctan2, …) 
The bulk of the diff is just factoring out the implementation
for binary arithmetic implementations, to be reused for binary
function calls.

David Nadlinger bc6fbecbda compiler, firmware: Do not expose abort() to kernels 
This was only exposed for the assert implementation, and
does not exist on Zynq.

whitequark 2648b1b7a1 firmware: migrate to Rust 1.28.0. 
This also updates / is a prerequisite for updating smoltcp.

Rationale for changes made:
  * compiler_builtins is now shipped in the rust prefix.
  * rustc's libpanic_unwind no longer works for us because it
    has a hard dependency on Box (and it's a horrible hack);
    fortunately, we only ever needed a personality function
    from it.
  * panic and oom handlers are now set in a completely different
    way.
  * allocators are quite different (and finally stable).
  * NLL caused internal compiler errors in runtime, so code using
    NLL was rewritten to not rely on it and it was turned off.

whitequark 02b8426f60 firmware: rename libboard to libboard_misoc. 
By analogy with libbuild_misoc. Hopefully one day it actually gets
moved to misoc...

the compiler and runtime.

whitequark bc22d1c009 firmware: libksupport → ksupport. 
The idea is that support libraries are called lib*, and the final
products that linked into an executable are not.
