[csa] Remove InnerAllocate and replace with non-folded allocations

This CL removes all uses of InnerAllocate (except memento allocations)
and replace with non-folded allocations. The change is based on the
fact that 1. Those InnerAllocates are not guarded by --allocation-folding
flag. 2. Hopefully the MemoryOptimizer can handle the folding and no
performance regression will happen.

Two special versions of InnerAllocate is still kept:
* One for memento allocations (renamed to InnerAllocateMemento).
* One for AllocateUninitializedJSArrayWithElements (renamed to InnerAllocateElements).
