ba26efb60c Implement filling drop in MIR 
Hopefully the author caught all the cases. For the mir_dynamic_drops_3 test case the ratio of
memsets to other instructions is 12%. On the other hand we actually do not double drop for at least
the test cases provided anymore in MIR.

With this commit we now finally execute all the leftover drops once some drop panics for some
reason!

a2557d472e Align pointers to DST fields properly 
DST fields, being of an unknown type, are not automatically aligned
properly, so a pointer to the field needs to be aligned using the
information in the vtable.

Fixes #26403 and a number of other DST-related bugs discovered while
implementing this.

bbe1d28496 Move the core MIR datastructures to librustc. 
This is done mostly so that we can refer to MIR types in csearch and other metadata related area.

dcb64b52a2 represent fat ptr operands as 2 separate pointers 
this does add some complexity, but to do otherwise would require unsized
lvalues to have their own allocas, which would be ugly.
