whitequark 3ce1826891 runtime: don't print debug messages to the UART. 
It takes ~4ms to print an empty log line because of how slow
the UART is. This makes the log timestamps useless for debugging
performance problems.

After this commit, it takes ~75us to print an empty log line instead,
which pessimizes test_rpc_timing by less than 2ms with tracing
enabled.

David Nadlinger bfbdba9205 compiler: Emit all-kernel_invariant objects as LLVM constants 
This enables constant propagation optimisations, as verified by
the included test case. This is only a first stop-gap measure, though;
we should support optimisation based on kernel invariants on a more
fine-grained level.

This reverts commit fee75bd50f.

LLVM does not have lround as a libcall and this inhibits LICM.

David Nadlinger 6e77f65d50 compiler: Clarify recv_rpc value names and documentation [nfc] 
Previously, the phi emitted for the pointer parameter to recv_rpc was –
rather confusingly – called "size", and the pseudo-code in the comment
had bit-rotted.
