[DWARFYAML] Rename checkListEntryOperands() to checkOperandCount(). NFC.

[Higuoxing]

Summary

This patch renames checkListEntryOperands() to checkOperandCount(), so
that we are able to check DWARF expression operands using the same
function.

Seems reasonable, but I think a better spelling of the name would be checkOperandNumber (no s) -- "check number of operands" vs "check operand number"

[Higuoxing]

checkOperandsNumber -> checkOperandNumber.

Thanks for reviewing!

I'd actually go one step further and call it checkOperandCount. I think checkOperandNumber to me suggests "check the number of the operand X". LGTM, with that tweak.
