Jordan Rupprecht 98a2ae7dad Reland [llvm-objdump] Use a counter for llvm-objdump -h instead of the section index.
This relands r374931 (reverted in r375088). It fixes 32-bit builds by using the right format string specifier for uint64_t (PRIu64) instead of `%d`.

Original description:

When listing the index in `llvm-objdump -h`, use a zero-based counter instead of the actual section index (e.g. shdr->sh_index for ELF).

While this is effectively a noop for now (except one unit test for XCOFF), the index values will change in a future patch that filters certain sections out (e.g. symbol tables). See D68669 for more context. Note: the test case in `test/tools/llvm-objdump/X86/section-index.s` already covers the case of incrementing the section index counter when sections are skipped.

Hans Wennborg 312c4a6e24 Revert r374931 "[llvm-objdump] Use a counter for llvm-objdump -h instead of the section index."
This broke llvm-objdump in 32-bit builds, see e.g.
http://lab.llvm.org:8011/builders/clang-cmake-armv7-quick/builds/10925

Jordan Rupprecht c526ff8a62 [llvm-objdump] Adjust spacing and field width for --section-headers
Summary:
- Expand the "Name" column past 13 characters when any of the section names are longer. Current behavior is a staggard output instead of a nice table if a single name is longer.
- Only print the required number of hex chars for addresses (i.e. 8 characters for 32-bit, 16 characters for 64-bit)
- Fix trailing spaces
