Joseph Ferano 5b39730f07 The init-once flag moves out of the namespace a program can write ...

The guard flag was named .init-once.<global>, and . and - are ordinary
symbol constituents, so (defvar .init-once.x i64 7) beside a computed x
emitted the same symbol twice: the dev build died at the assembler on both
backends, and the flag's Bool was registered over the user's global in
Emit.globals so the store came out as an i1. It is .init~once.<global> now;
~ terminates a symbol in the reader, the same trick destructure~N uses.
test/programs/dev-rerun.flan carries such a global and no new printed line.

Three places said a defconst is the linker's image on one backend and a
constructor's stores on the other and a re-run reaches neither. Tast.const_init
splits on the initialiser and not on the form, so that holds only for a
constant initialiser; a computed defconst is guarded like a defvar on x86 and
refused outright by emit.ml's const. The sentences now say that, including
the divergence.

emit.ml also claimed Check.no_transfer_in_init made it impossible to leave the
guarded branch between the store and the flag. It is syntactic over the
written initialiser only: a callee can signal unhandled and take the call's
transfer edge out, leaving the flag false — which is what should happen, since
the next run retries. Read off the emitted IR for such a program.

The x86 float-Rem comment says why the dead movabs before fmod is kept, and
its mid-sentence line break is gone; math3.flan's first float-% line prints
six values, not four.
