[nfc] [lldb] DWARFDebugInfoEntry::Extract(): reindent

Commit 1b6eb56aa0ea2931866455a21a138fc09c08e905 by thomasp
Stop traping on sNaN in __builtin_isinf

__builtin_isinf currently generates a floating-point compare operation
which triggers a trap when faced with a signaling NaN in StrictFP mode.
This commit uses integer operations instead to not generate any trap in
such a case.

[AA] Cache (optionally) estimated PartialAlias offsets.

For the cases of two clobbering loads and one loaded object is fully contained
in the second `BasicAAResult::aliasGEP` returns just `PartialAlias` that
is actually more common case of partial overlap, it doesn't say anything about
actual overlapping sizes.

AA users such as GVN and DSE have no functionality to estimate aliasing of GEPs
with non-constant offsets. The change stores estimated relative offsets so they
can be used further.
