which remembered the last {AssemblerBuffer} on {Grow()}. Since the
{Assembler} itself already keeps track of the latest {AssemblerBuffer},
this functionality is mostly redundant. All we need instead is a method

The change is made since for switch statements with lots of cases,
where each case is a constant integer, the emitted bytecode is still
a series of jumps, when we can instead use a jump table.

If there are 6 or more cases (similar to GCC) of Smi literals, and
if the max Smi case minus the min Smi case is not more than 3 times
the number of cases, we use a jump table up front to handle Smi's,
and then use traditional if-else logic for the rest of the cases.

We then use the jump table in interpreter/bytecode-jump-table to
do the optimization.

This tries to go off issue 9738 in v8's issue tracker. It is not
exactly the same, since that recommends doing the work at JIT-time,
but has similar ideas. It also partially goes off issue 10764.

In the first CL to introduce a histogram for deserialization time a
high-resolution counter was required to get microsecond precision.
However, with the histogram we want to detect if we need to optimize
deserialization or not. For this information high precision does not
matter, it is more important that we get information from all devices.

This partially reverts https://crrev.com/c/2649032
The previous CL was a bit too aggressive in replaceing movl with Move
which does sign extension for int32.

We can only safely replace movl if the input is in the [0, 2**31] range.

Add a similar check used in vlbr to make sure offset is
a 12 bit unsigned integer.

  - Asynchronously load source map from sourceMappingURL
  - Once loaded, annotate source positions with their original position
  - Update script panel tooltip to include link to original source
     - For the above, make DOM.element a slightly more flexible API,
       allowing defining attributes and children
     - Also fix ToolTipEvent handling to support nodes.
  - Shuffle around some code to make createScriptNode async, in case
    we want to load the source map when building the script node itself.
  - Drive-by: make source markers a simple backgroundColor when there is
    only one group.

Now that SimpleStringBuilder is only used in conversions.cc, it can be
moved there making it easier to assess its safety and limit further
use of this potentially unsafe API. (Additionally unused methods Reset
and size are removed).
