errors caught by ecl bytecode compiler

[Qian Yun]

I'm combining all interp files into one and use ECL to
bytecode compile it, and it finds several errors:

1. "systemError" takes 1 argument, but in several places
it is called without argument: "systemError()"

2. "throwKeyedMsg" in definition of "upLoopIters" is called
with 1 argument instead of 2.

3. "bcNotReady" in definition of "bcSeriesByFormulaGen"
is called with 0 argument instead of 1.
