Behavior in Release mode was correct; Debug mode triggered a DCHECK
failure that indicated an inefficiency: when a requested truncation
would be a no-op, we should return the original BigInt, rather than
creating a copy. In the special case of -2^(n-1), i.e. the smallest
negative n-bit integer, getting truncated to n bits, with n being a
multiple of kDigitBits, this shortcut was not taken.

Since we use a ScopedPtrList to track cover grammar expressions we don't know
the position of the commas anymore. The position of the commas was used to
demark the initializer, which is needed to figure out whether we need hole
checks for variable references. (Typically only references within the
initializer need hole checks for the initialized variable.) Since we didn't
have the comma position, we simply used the position of the first expression as
the position of any subsequent comma, which would make it seem as if the
initializer body wasn't in the initializer. Now instead we simply use the
position of the subsequent parameter as the end of the initializer, which is
close enough.

The Ignition statement list visitor will skip the rest of the
statements in the list if it hits a jump statement (like a return
or break), as the rest of the code in the list can be considered
dead.
return;
dead_call(); // skipped
However, since this is at an AST node level, it does not take into
account condition shortcutting:
if(2.2) return;
dead_call(); // not skipped
There is also a second dead code elimination in Ignition compilation, at
the bytecode array writer level, where a bytecodes are not emitted if an
"exit" bytecode (Return, Jump, or a few others) has been written, until
the next basic block starts (i.e. a Bind).
This can cause an issue with statements that resurrect the bytecode
array writer part-way through their visit. An example is try-catch
statements, which save the context to a register, and then Bind to start
the try region.
For the case:
if (2.2) return;
try { // try statement not skipped
...
}
the bytecode writer is called with
OutputReturn() // exit bytecode seen
OutputMove(<context>, r1) // not emitted
Bind(&try_begin) // starts new basic block
// try body
So, the try is emitted, but without saving the context to a register.
This means that the liveness analysis sees the read of that register
(as the output liveness of throwing bytecodes), but does not have a
write to the register, which means that the liveness escapes.
This patch fixes this by using the bytecode array writer dead-code
elimination (i.e. "exit bytecode seen") to inform the statement list
visitor, so that in this example the try statement is not visited at
all.

Previously, we finalize all compile jobs at once. This keeps the zone memory
in every compile job alive until the end. This contributes to a high peak
memory when many functions are compiled eagerly, for example when producing

Memory tracked by the AccountingAllocator in bytes, prior to this change in
the test case:
peak memory after init: 8192
peak memory after lazy compile: 41200
peak memory after lazy compile: 41200
peak memory after eager compile: 164256
With this change, if we are compiling on the main thread, we finalize every
compile job as soon as it is done and dispose the compile job and its zone
memory.
After this change:
