Mehdi Amini 1c131b37ed Instcombine: destructor loads of structs that do not contains padding
For non padded structs, we can just proceed and deaggregate them.
We don't want ot do this when there is padding in the struct as to not
lose information about this padding (the subsequents passes would then
try hard to preserve the padding, which is undesirable).

Also update extractvalue.ll and cast.ll so that they use structs with padding.

Remove the FIXME in the extractvalue of laod case as the non padded case is
handled when processing the load, and we don't want to do it on the padded
case.

Mehdi Amini 2668a487a7 Update InstCombine to transform aggregate loads into scalar loads.
Summary:
One step further getting aggregate loads and store being optimized
properly. This will only handle struct with one element at this point.

Test Plan: Added unit tests for the new supported cases.
