Jake Bailey 5ba8766cbc compiler: implement method-set based AssignableTo and Implements (#5304)
* reflect: implement method-set based AssignableTo and Implements

Based on the design from #4376 by aykevl.
Fixes #4277, fixes #3580.

Co-authored-by: Ayke van Laethem <aykevanlaethem@gmail.com>

* builder: update expected binary sizes for reflect changes

* Make interface checks similar to invoke, allowing typeImplementsMethodSet and method info to be dropped when reflect is not present

* Add more tests that BigGo reflect tests

* Even more pruning

* Add go/token and net/url to passing tests

* Prune even further, I am less happy with this, though

* Update size test now that we are smaller

* Skip some tests

* elide method lists

* format, oops

* fix tests

* Add a panic, pull out constant to keep in sync

* Add debug info

* Remove code that was leftover from a previous refactor

Ayke van Laethem 404b65941a transform: move tests to transform_test package
This allows for adding more advanced tests, for example tests that use
the compiler package so that test sources can be written in Go instead
of LLVM IR.

Ayke van Laethem bcce296ca3 transform: optimize reflect.Type Implements() method
This commit adds a new transform that converts reflect Implements()
calls to runtime.interfaceImplements. At the moment, the Implements()
method is not yet implemented (how ironic) but if the value passed to
Implements is known at compile time the method call can be optimized to
runtime.interfaceImplements to make it a regular interface assert.

This commit is the last change necessary to add basic support for the
encoding/json package. The json package is certainly not yet fully
supported, but some trivial objects can be converted to JSON.

Ayke van Laethem f9865a08bc transform: optimize string comparisons against ""
This optimizes a common pattern like:

    if s != "" {
        ...
    }

to:

    if len(s) != 0 {
        ...
    }

This avoids a runtime call and thus produces slightly better code.
