[Object/llvm-readobj] - Cleanup testing of the dynamic objects.

[grimar]

Summary

This patch touches a few test cases:

1. It removes dtflags.elf-x86-64 binary and elf-dtflags.test.

elf-dtflags.test is excessive because we have the
elf-dynamic-tags.test which test all non-machine specific tags.

2. It removes testing of --dynamic-table from test\Object\readobj-shared-object.test

(we have the elf-dynamic-tags.test for that), and simplifies this test case.

3. It moves testing of the headers from readobj-shared-object.test

to elf-file-headers.test.

4. Adds test/tools/llvm-readobj/elf-file-types.test and test/tools/llvm-readobj/elf-loadname.test.

It opens road for removing the readobj-shared-object.test completely soon.

Do we have testing elsewhere for this part of the printing?

Seems like this should be a separate NFC commit? This file is otherwise unchanged.

It feels like the machine type and ELF type are two orthoganol test cases that don't need combinatorially testing. Why not also test ET_EXEC and ET_CORE in this manner after all?

Perhaps a separate test file would be sensible, with tests for each different ELF type, focused just on testing that field?

Probably not. I Added elf-loadname.test.

I just tried to show this test case in the commit somehow since I am referring to it.
Reverted.

I added a separate test.

You should probably also test something in the ET_LOOS -> ET_HIOS range too.

Interesting that ELF.h doesn't define ET_LOOS/ET_HIOS:

// File types
enum {
  ET_NONE = 0,        // No file type
  ET_REL = 1,         // Relocatable file
  ET_EXEC = 2,        // Executable file
  ET_DYN = 3,         // Shared object file
  ET_CORE = 4,        // Core file
  ET_LOPROC = 0xff00, // Beginning of processor-specific codes
  ET_HIPROC = 0xffff  // Processor-specific
};

LGTM.
