Mythri A 9fe37d238e Reland [ic] Remove the check for fast prototypes in LoadIC_Uninitialized 
This is a reland of d14ed12e56
with fix for test failures in lite mode.

When handling load named properties (without feedback vectors) we used
to miss to runtimes if the prototypes aren't set. This was because we
wanted to give the prototype a chance to become fast, since most prototypes
start in slow mode but move to fast after the initial setup. Though this
check is not really useful when we don't have feedback vectors, and once
feedback vectors are allocated we will turn the prototypes fast anyway.
