Unfortunately, the olin/cwa emulator does not handle floats correctly.
Node.js does, and because it is also supported by the Go WebAssembly
implementation it has better support in general.
CircleCI is faster and has more features than Travis CI. Additionally,
based on the recent news, the future of Travis CI is rather uncertain.
Keep using Travis CI for macOS testing at the moment, as open source
projects will need to get special permission to use CircleCI for macOS
tests.
The interp package does a much better job at interpretation, and is
implemented as a pass on the IR which makes it much easier to compose.
Also, the implementation works much better as it is based on LLVM IR
instead of Go SSA.
Match data layout of complex numbers to that of Clang, for better
interoperability. This makes alignment of complex numbes the same as the
individual elements (real and imaginary), as is required by the C spec
and implemented in Clang, but unlike the gc compler. The Go language
specification is silent on this matter.
> Each complex type has the same object representation and alignment
> requirements as an array of two elements of the corresponding real
> type (float for float complex, double for double complex, long double
> for long double complex). The first element of the array holds the
> real part, and the second element of the array holds the imaginary
> component.

The math package uses routines written in Go assembly language which
LLVM/Clang cannot parse. Additionally, not all instruction sets are
supported.
Redirect all math functions written in assembly to their Go equivalent.
This is not the fastest option, but it gets packages requiring math
functions to work.
LLVM supports both "ordered" and "unordered" floating point comparisons.
The difference is that unordered comparisons ignore NaN and produce
incorrect results when presented with a NaN value.
This commit switches these comparisons from ordered to unordered.

There were a few issues that made interp not perform as it should:
* The scan was non-recursive due to a bug.
* Recursive scanning would always return the severity level, which is
not always the best strategy.
The interp package interprets calls in runtime.initAll and replaces
these calls with non-interpretable instructions if needed.
When hitting an unreachable instruction, this call should be removed,
but it wasn't. This commit makes sure the call is removed even before
trying to interpret the package init function.
