Sathya Gunasekaran 28f3d23658 [turboprop] Introduce a builtin to perform dynamic map checks
Instead of always inlining the polymorphic map checks, this CL
introduces a builtin to perform these polymorphic map checks
when the IC is monomorphic at compile time.

This reduces the time we spend compiling and code bloat while trading it
for performance.
