[LoadStoreVectorizer] Only upgrade align for alloca
In commit 2be0abb7fe72ed453 (D149893) the load store vectorized was
reimplemented. One thing that can happen with the new LSV is that
it can increase the align of alloca and global objects. However,
the code comments indicate that the intention only was to increase
alignment of alloca.
Now we will use stripPointerCasts to analyse if the load/store really
is accessing an alloca (same as getOrEnforceKnownAlignment is using).
And then we only try to change the align if we find an alloca
instruction. This way the code will match better with code comments,
and we won't change alignment of non-stack variables to use the
"StackAdjustedAlignment".
