"doFASM" is a variable word whose value is the implementation of the
execution semantics for assembly code implemented words. In those
cases the execution leads to the word content.

The register context at entry to an assembly code implemented word is
as follows:

----
    rax = cfa* of word to execute
    rsi = cell* in the calling definition, after calling cell
    rsp = data stack pointer
    rbp = return stack pointer
----

The assembly code must ensure that +rsi+ is preserved and that +rsp+
and +rbp+ are used according to their roles.
