  [ValueTracking] Remove AllocaForValue parameter

findAllocaForValue uses AllocaForValue to cache resolved values.
The function is used only to resolve arguments of lifetime
intrinsic which usually are not fare for allocas. So result reuse
is likely unnoticeable.

In followup patches I'd like to replace the function with
GetUnderlyingObjects.

Depends on D84616.
