return exactly the same value. Since the {begin} method is needed for

switches all uses of the {start} method to use {begin} instead.

callExpr(
callee(
cxxMethodDecl(
hasName("start"),
ofClass(hasName("v8::internal::Vector")))
),
argumentCountIs(0))
Patchset 2 was created by running clang-format. Patchset 3 then
removes the now unused {Vector::start} method.

Code object iteration was missing logic for RELATIVE_CODE_TARGET
reloc entries. Garbage collection could thus miss objects that were
referenced only as targets of pc-relative calls or jumps.
RELATIVE_CODE_TARGETs are only used on arm, mips, and s390 and only
at mksnapshot-time.
This exposed another issue in that the interpreter entry trampoline
copy we generate for profiling *did* contain relative calls in
runtime-accessible code. This is a problem, since code space on arm is,
by default, too large to be fully addressable through pc-relative
calls. This CL thus also disables the related
FLAG_interpreted_frames_native_stack feature on arm.
Drive-by: Ensure the builtins constants table does not contain Code
objects.

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.
