Support the type profiler in the DFG
https://bugs.webkit.org/show_bug.cgi?id=136712
Reviewed by Filip Pizlo.
This patch implements op_profile_type inside the DFG as the node: ProfileType.
The DFG will convert the ProfileType node into a Check node in the cases where
passing a type check is equivalent to writing to the TypeProfilerLog. This
gives the DFG the potential to optimize out multiple ProfileType nodes into
a single Check node.
When the DFG doesn't convert ProfileType into a Check node, it will generate
the same inline code as the baseline JIT does for writing an entry to the
TypeProfilerLog.

Make this method public so others can reason about the types a TypeSet has seen.

Renamed to dumpTypes so the method seenTypes can be used as a public getter.
