grimar added a child revision: D68086: [llvm-readelf] - Report a warning when .hash section contains a chain with a cycle..

SHT_HASH specification is:
https://docs.oracle.com/cd/E23824_01/html/819-0690/chapter6-48031.html

In short the format is the following: it has 2 uint32 fields in its header: nbucket and nchain followed
by (nbucket + nchain) uint32 values.

This patch allows dumping and parsing such sections.
