L. Pereira 417a26d20c runtime: Simplify slice growing/appending code (#4287)
* reflect: rawFieldByNameFunc: copy index slice to avoid later overwrites

* runtime: Simplify slice growing/appending code

Refactor the slice appending function to rely on the slice growing
function, and remove branches/loops to use a branchfree variant.

* runtime: Remove one branch in sliceAppend()

Both branches were equivalent, so guard the overall logic in
sliceAppend() with the more general condition.

* runtime: Simplify slice growing calculation

Use `bits.Len()` rather than `32 - bits.LeadingZeros32()`.  They're
equivalent, but the Len version is a bit easier to read.

* reflect: Always call sliceGrow() in extendSlice()

sliceGrow() will return the old slice if its capacity is large enough.

Ayke van Laethem 5b42871baa compiler: support all kinds of recursive types
Previously we only supported recursive types in structs. But there can
be other kinds of recursive types, like slices:

    type RecursiveSlice []RecursiveSlice

This doesn't involve structs, so it led to infinite recursion in the
compiler. This fix avoids recursion at the proper level: at the place
where the named type is defined.
