Alexander Markov 13aaaae1b2 [vm/compiler] Introduce AllocateTypedData IL instruction
This is the first step towards optimizing typed data array allocations,
which is useful for e.g. package:vector_math.

Opaque call to a typed data factory constructor is replaced with IL
instruction which doesn't have side-effects and doesn't prevent
other optimizations (e.g. load forwarding) from happening.

Asm intrinsics for typed data factories are replaced with stubs.
