Update the documentation for the merger, and also for various changes in Cranelift. Remove some old obsolete documentation, and convert the remaining Sphinx files to Markdown. Some of the remaining content is still out of date, but this is a step forward.
This crate provides a straightforward way to create a
Cranelift IR function and fill it with
instructions translated from another language. It contains an SSA construction
module that provides convenient methods for translating non-SSA variables into
SSA Cranelift IR values via use_var and def_var calls.
