SUMMARY:
when there are two symbol has the same address. llvm-objdump -D -symbol-description will select symbol based on the following rule:
1. using Label first if there is a Label symbol.
2. If there is not Label, using a symbol which has Storage Mapping class.
3. if more than one symbol has storage mapping class, put the TC0 has the low priority, for other storage mapping class , compare based on the value.

This patch intends to fix incomplete relocation printing for
XCOFF (potentially for other targets).
Differential Revision: https://reviews.llvm.org/D77580
SUMMARY:
For the llvm-objdump -D, the symbol name is used as a label in the disassembly for the specific address (when a symbol address is equal to the virtual address in the dump).
In XCOFF, multiple symbols may have the same name, being differentiated by their storage mapping class. It is helpful to print the QualName and not just the name when forming the output label for a csect symbol. The symbol index further removes any ambiguity caused by duplicate names.
To maintain compatibility with the binutils objdump, the XCOFF-specific --symbol-description option is added to enable the enhanced format.

Summary:
When we encounter an XCOFF file, reflect that in the triple information.
In addition to knowing the object file format, we know that the
associated OS is AIX.
This means that we can expect that there is no output difference in the
processing of an XCOFF32 input file between cases where the triple is
left unspecified by the user and cases where the user specifies
`--triple powerpc-ibm-aix` explicitly.
