erts: Fix loading of modules with invalid floating point arithmetic
The following program is supposed to cause an exception
at run-time:
foo() ->
Sum1 = Sum2 = N = 2,
pSum - (Sum1*(Sum2/N)).
but the loader fails to load because it contains the
following instruction:
fconv {atom,pSum} {fr,2}
Fix the loader so that it can handle fconv instructions
where the first operand is a non-numeric literal.
