We have internal::TickSample which inherits from this, but we never
use the public version in the API despite defining it there.

This CL was generated by an automatic clang AST rewriter using this
matcher expression:
callExpr(
callee(
cxxMethodDecl(
hasName("operator->"),
ofClass(isSameOrDerivedFrom("v8::internal::Object"))
)
),
argumentCountIs(1)
)
The "->" at the expression location was then rewritten to ".".

This CL introduces a new gn argument: v8_enable_pointer_compression which is
false by default. All the changes done in this CL are made under this flag.
Upper half-word of a Smi word must be properly sign-extended according to the
sign of the lower-half containing the actual Smi value.

The "Address" type is V8's general-purpose type for manipulating memory
addresses. Per the C++ spec, pointer arithmetic and pointer comparisons
are undefined behavior except within the same array; since we generally
don't operate within a C++ array, our general-purpose type shouldn't be
a pointer type.

... or sometimes by FATAL(...) to give a better error message.
The benefit of UNREACHABLE() over CHECK(false) is that the compiler
knows that this macro will never return, hence we can omit the return
of a dummy value afterwards.

We want to eventually move the profiling functionality out of V8 as library,
this patch exposes TickSample and its APIs in v8-profiler.h so that when
embedders use library, they can have more details.
Minor change: Rename tick-sample.[h|cc] to simulator-helper.[h|cc].
