      [sparkplug] Inline TypeOf checks · d7ed4f97
      Leszek Swirski authored 
      In the TestTypeOf handler, use the statically known value of the type-of
literal flag to emit the specific type-of check for that type, rather
than going to the general type-of builtin. These checks are very simple,
so we can get away with hand-writing them in the baseline compiler.

      Reland "[sparkplug] Change bytecode offset mapping and introduce iterator." · 2966c896
      pthier authored 
      This is a reland of a8b61ef5

The main reason for the revert was not related to this CL and was fixed
with https://crrev.com/c/2739646
In addition debug output in d8.test.verifySourcePositions was removed
due to TSAN complaints.

      Previously, we recorded pairs of (bytecode offset, sparkplug pc) to
create a mapping of bytecode offset <-> sparkplug pc.
These pairs were only recorded after builtin/runtime calls.
In preparation for deoptimizing to Sparkplug, we need a more precise
mapping.
With this CL, we record positions for every bytecode. Instead of storing
a pair of (bytecode offset, sparkplug pc), we store only the pc,
calculating the bytecode offset from the index in the mapping table.
For easier use an iterator to access the mapping is introduced.

Drive-by: Reduce sampling interval in cpu-profiler cctest to get rid of
flaky failures.
