  * floating point -> integer conversions.
    x86 defines that overflow/underflow
    results in 1<<15, 1<<31, 1<<63 for
    int16, int32, int64.  when building the
    unsigned conversions out of the native signed
    ones, 8g turns overflow/underflow into zero.
    the spec does not say what should happen.

  * many tiny bug fixes.  can run a large number
    of files from go/test now, and can fmt.Printf.

  * struggling with byte register allocation
    and float32 computation.

avoid tight coupling between deferreturn and jmpdefer.
before, jmpdefer knew the exact frame size of deferreturn
in order to pop it off the stack.  now, deferreturn passes
jmpdefer a pointer to the frame above it explicitly.
that avoids a magic constant and should be less fragile.

auto-generated files and deletions are in another CL.

goals for new syscall:
	* automate as much as possible
	* do not let clients do unsafe things
	* use simple types (int not int64)
	* fewer files

the files are renamed from foo_amd64_linux to foo_linux_amd64,
both because it reads better (all the linux are related, all the amd64 less so)
and because it made it easier to replace the existing ones.

The change to assign.go is because the gcc testsuite fails to
handle .* in a normal way: it matches against the entire
