George Burgess IV 48ee59b6f0 [DeadArgElim] Remove allocsize attributes on callsites 
We're already removing allocsize attributes from Functions that we
remove args from, since removing arguments from a function may make the
allocsize attribute incorrect. It appears we forgot to also remove them
from callsites.

Without this, I get verifier errors on `@Test2`.

It probably wouldn't be too hard to make DAE properly update allocsize
attributes instead of dropping them, but I can't think of a scenario
where that'd be useful in practice.

Benjamin Kramer 8840f644b4 [DeadArgElim] Strip allocsize attributes when deleting an argument. 
Since allocsize refers to the argument number it gets invalidated when
an argument is removed and the numbers shift.
