Previously we used the start address of the AbstractCode object. This
doesn't make sense for off-heap builtins, where the code isn't contained
in the object itself. It also hides other potential problems - sometimes
the sample.pc is inside the AbstractCode object header - this is
never valid.
There were a few changes necessary to make this happen:
- Change the interface of CodeMoveEvent. Now 'to' and 'from' are both
AbstractCode objects, which is nice because many users were taking
'to' and adding the header offset to it to try and find the
instruction start address. This isn't valid for off-heap builtins.
- Fix a bug in CodeMap::MoveCode where we didn't update the CodeEntry
object to reflect the new instruction_start.
- Rename the 'start' field in all of the CodeEventRecord sub-classes
to make it clear that this is the address of the first instruction.
- Fix the confusion in RecordTickSample between 'tos' and 'pc' which
caused pc_offset to be calculated incorrectly.

This reverts commit 51ad234ffe.
Reason for revert: Speculative revert. Suspect for layout test change:

See also:

MIPS64 doesn't support 32-bit compare operations, instead it
relies that values in registers are properly sign extended to
64-bit. Sign extending and then comparing is a costly operation
that we want to avoid. We use costly compare only in those cases
when one operand is signed and other is unsigned.
This CL adds marks PoisonedLoad and ProtectedLoad of unsigned
values as needing full compare instead of optimized one.

wildcards, but is relatively slow. For given test names that don't
contain any '*', we can use string equality testing, which is much
faster.
Example: the time to evaluate
