Pass on the incoming arguments descriptor when invoking an irregexp function. Avoiding loading an arguments descriptor in the intrinsic code also allows generated regexp code in precompiled code. Loading a new descriptor is not necessary since the arguments are already on the stack in the right order. Use named constants for parameter indices in the regexp assembler.
