  [Statepoints] Unlimited tied operands.

Current limit on amount of tied operands (15) sometimes is too low
for statepoint. We may get couple dozens of gc pointer operands on
statepoint.
Review D87154 changed format of statepoint to list every gc pointer
only once, which makes it trivial to find tiedness relation between
statepoint operands: defs are mapped 1-1 to gc pointer operands passed
on registers.
