Accessing PIR opcodes directly from NQP (pir::)

• NQP provides a pir:: pseudo-namespace for direct access to PIR opcodes

my $ord := pir::ord('A')

• Signature suffixes allow the operands to be coerced

# "Iss" == pass two strings, returning an int
my $offset := pir::index__Iss(':', $str);

• In the near future, we plan to provide a nqp:: pseudo-namespace to abstract away from PIR or the underlying VM

my $elems := nqp::elements(@array);
