Inline recognized List factory in the flow graph optimizer.
...
The call to the native List factory is lowered into IL instructions if
the length is known to be a valid smi.
This is mostly performance neutral. The acutal allocation now takes place
in the array allocation stub instead of the intrinsic code (and the runtime
List_allocate in case the fast case path fails).
This is a preparation for enabling allocation sinking for arrays and will
be extended to handle type list allocation as well. This way the allocation
site is explicitly represented as a CreateArrayInstr, instead of just being
a static call.
Another benefit is that this allows to simplify the special handling of
recognized factory calls in the optimizer once all array types are handled
this way.

Fix stack height assertion code and free up a bit in the Function tag bits.
...
The bit has_finally was only used to skip the checking of the stack height
at return statements: There was an unused value floating on top of the
expression stack in unoptimized code if the finally block preceded a normal
return statement. Normallyi, that does not cause harm. Optimized code is not
affected since it has a fixed stack size for expression evaluation.
This CL fixes the stack height for functions with try-finally by introducing
a temporary local where the return value is saved before an inlined
finally-block.

Improve aliasing info for load elimination of array loads.
...
The optimizer can now track side effects to array locations
at a constant index when eliminating array loads. Stores to
arrays with a constant index affect loads from arrays
at the same constant index _and_ loads from an unknown (non-constant)
index. Stores to an array with an unknown index affect all array loads.
For instance code like
var a = new List(2);
a[0] = 123;
a[1] = 456;
print(a[0] + a[1]);
we can now eliminate both loads from a[0] and a[1], where before
only the loads from a[1] was eliminated.
I changed the internal encoding of Alias to use BitField instead of
plain integers. This makes it a little easire to extend.
