already. Convert the rest. In general, try to place the build constraint
line below the test directive comment in more places.

If OpArgIntReg is incorrectly scheduled, that causes it to be spilled
incorrectly, which causes the argument to not be considered live
at the start of the function.
This is the test for CL 462858
Add a brief mention of why CL 462858 is needed in the scheduling code.

Sort variables before display so that when there are multiple variables
to report, they are in a consistent order.
Otherwise they are ordered in the order they appear in the fn.Dcl list,
which can vary. Particularly, they vary depending on regabi.

With the introduction of stack objects, VARKILL information is
no longer needed.
With stack objects, an object is dead when there are no more static
references to it, and the stack scanner can't find any live pointers
to it. VARKILL information isn't used to establish live ranges for
address-taken variables any more. In effect, the last static reference
*is* the VARKILL, and there's an additional dynamic liveness check
during stack scanning.
Next CL will actually rip out the VARKILL opcodes.

Unified IR will soon introduce additional temporary variables for
multi-valued expressions, which cause this test to start failing.
However, according to the comment on lines 594--596, we don't care
what temporaries are printed on the noisy lines, just that they're not
mentioned on the printnl lines.
This CL relaxes the test expectations so that temporaries are allowed
to be live at the call to fb38() too, not just the calls to fi38() and
fc38().

Simplify the implementation of interface conversions in the compiler.
Don't pass fields that aren't needed (the data word, usually) to the runtime.
For generics, we need to put a dynamic type in an interface. The new
dataWord function is exactly what we need (the type word will come
from a dictionary).

Similar to the previous CL to suppress escape analysis diagnostics for
method wrappers, suppress liveness analysis diagnostics too. It's
hardly useful to know that all of a wrapper method's arguments are
live at entry.
