Tess Strickland a02596b28f [vm,dyn_modules] Source position cleanups and fewer temp uses. 
Reduces the usage of temps in the following cases to remove unneeded
StoreLocal/Push instructions:

Refactors visitVariableSet so that a temporary is used only if the
variable is captured and the result is not ignored. (That is,
sets of uncaptured late final fields no longer need a temporary.)

Only allocate a temp for FunctionDeclarations and FunctionExpressions
if there are function type arguments to capture or if the function
is generic (in which case the delayed type arguments field must be
empty-initialized, not null initialized).

-----

Clean up how source positions are emitted to both be more consistent
and to also move some source position emissions closer to the actual
instruction that performs the operation:

Move emission of debugging information for FunctionDeclaration,
and VariableSet to when the variable is actually set. The emission
in VariableDeclaration stays before the initializer as that's when
debugger tests expect to pause at it.

Change the implementation of _genConditionAndJumpIf to use if/else
chaining instead of early returns so that the condition's source
position can be recorded once before the if/then chain and then the
previous source position restored afterward the chain. This means
that _emitDebuggerInformation can be used.

_generateNonLocalControlTransfer is only called during visit methods
where the parent call to _generateNode has already recorded the from
node's position, so there's no need to record it during that call.
Instead, move the emission of the source position to the jump within the
passed continuation.

Remove _emitLocalSourcePosition, since it is no longer used.
