e34b723d3e A debug function start was not being recorded when the optimization level wasn't
None. However, we were always recording the region end. There's no longer a good
reason for this code to be separated out between the different opt levels, as it
was doing pretty much the same thing anyway.

6c4311dddb Mirror how Fast ISel determines if a region.end intrinsic is the end of an
inlined function or the end of a function. Before, this was never executing the
"inlined" version of the Record method.

This will become important once the inlined Dwarf writer patch lands.

e688fafd38 Compute the offsets of the compile units. We need this so that when we emit a
concrete instance of an inlined function, we can get the actual address of the
abstract instance inside of the compile unit.

This isn't currently used, but will be by a future check-in.

ef554846f0 fix RewriteStoreUserOfWholeAlloca to use the correct type size
method, fixing a crash on PR4146.  While the store will 
ultimately overwrite the "padded size" number of bits in memory,
the stored value may be a subset of this size.  This function
only wants to handle the case where all bits are stored.
