Jakob Kummerow 4e2954ee57 [ptr-compr] Fix Torque/CSA version of CreateTypedArray 
There is a copy of the pointer decompression logic in
TypedArrayBuiltinsAssembler::SetJSTypedArrayOnHeapDataPtr,
which was not updated for the new ("smi-corrupting") pointer
compression scheme: it erroneously used a sign-extending cast
from compressed to full representation. This causes incorrect
values to be computed when the heap size can grow beyond 2GB.
