[PATCH] D130315: [DWARF][BOLT] Implement new mechanism for DWARFRewriter

[Rui Zhong via Phabricator via llvm-commits]

zr33 updated this revision to Diff 448213.
zr33 added a comment.

1. Rewrite finding TypeDIE part. It used find by traverse the tree and find by Attribute name.

However, this is not accurate because a type unit can have multiple Attributes which can be TypeDIE, but there is only 1 can represent the Type Unit. 
Currently, the TypeDIE is record during IR construction.

2. Re-calibrate the cross-CU reference in case there are type units in .debug_types section.

3. clean up code and fix nits.
