rGb236b4cb4306: [yaml2obj] - Set a default value for `PAddr` property of a program header to a…
Summary

PAddr corresponds to p_paddr of a program header, which is the segment's physical
address for systems in which physical addressing is relevant. p_paddr is often equal
to p_vaddr, which is the virtual address of a segment.

This patch changes the default for PAddr from 0 to a value of VAddr and adds a test.

Some post-commit comment comments. Otherwise looks fine.

llvm/test/tools/yaml2obj/ELF/program-header-address.yaml
30

Show what virtual and physical address we set by default for the case where a program header

(same below)

31

has no sections included -> has no sections

41–42

different from a address -> different to the address

43

to the program header's virtual address
