As the interpreter matures it will hopefully be merged into the regular
jit configuration, but for now we make a separate configuration for it.

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.

This reverts commit f13f772bb2.
Reason for revert: dartk(p)-strong debug mode is completely broken
because we convert int values non-representable as Smi to Smi, which
triggers that assert. The code that does tagging checks that
Untag(Tag(x)) == x, however for our purposes this identity does not
need to hold because we only care about lower bits and ignore the sign.
Reverting to restore green-ness of DEBUG builds.
