This allows the compiler to emit better errors. It also allows the
compiler to detect when a class accidentally references its own
supposedly disallowed constructors/operators (e.g., see dartutils.cc).
Notably, this exposes a number of private member variables that are
unused, but some that are used only in certain build configurations.
It would arguably be better to only define the variables when they're
needed, but that's deferred to a subsequent CL.

Internal builds in Google are catching this as an error.
I'm guarding it because I assume we might support building using other
compilers.

When logical expression is evaluated in the control context (e.g. if (cond) { ... })
avoid materializing a boolean value and then dispatching on it. Instead connect
true and false successors directly to then and else branches.
This CL also improves IL generated when logical expression is evaluated for value
(e.g. x = (cond)): we similarly avoid materializing intermediate results and also
avoid comparisons that are not needed, e.g. when evaluating x = A && B we construct
graph x = A ? B : false, instead of x = A ? (B == true ? true : false) : false style
of graph.

Since the kernel reading helpers have been extended to not only work
with a kernel blob in C heap, but also work based on a [TypedData]
buffer in the VM heap, access to the [TypedData] buffer is on the hot
path now.
This hot path is slowing things down considerably, in particular due
to NoSafepoingScope's.
This CL removes a critical NoSafepoingScope when accessing the
[TypedData] in read-only mode. It also allows passing in the [Thread]
directly, to avoid TLS lookups.

This CL corrects handling of overflows in range analysis to
account for wrap-around (which happens with new integer semantics).
* If there is an overflow while doing computations in range
analysis, the resulting range is approximated as full int64 range.
* For symbolic range boundaries 'symbol + offset', offset is checked
to stay within [kMinInt64 - kSmiMin, kMaxInt64 - kSmiMax] in order
to guarantee that overflow doesn't occur.
