948209eab7 Stop inventing symbol sizes. 
MachO and COFF quite reasonably only define the size for common symbols.

We used to try to figure out the "size" by computing the gap from one symbol to
the next.

This would not be correct in general, since a part of a section can belong to no
visible symbol (padding, private globals).

It was also really expensive, since we would walk every symbol to find the size
of one.

If a caller really wants this, it can sort all the symbols once and get all the
gaps ("size") in O(n log n) instead of O(n^2).

On MachO this also has the advantage of centralizing all the checks for an
invalid n_sect.

dfd6ce5dd4 For llvm-objdump, with the -archive-headers and -macho options, use the -non-verbose 
option to print the archive headers using raw numeric values.  Also add the -archive-member-offsets
for use with these to also trigger printing of the offset of the archive member from the start
of the archive.

2bc88f43cf Add the option -objc-meta-data to llvm-objdump used with -macho to 
print the Objective-C runtime meta data for Mach-O files.

There are three types of Objective-C runtime meta data, Objc2 64-bit,
Objc2 32-bit and Objc1 32-bit.  This prints the first of these types. The
changes to print the others will follow next.

b55ba922b2 Add the option, -non-verbose to llvm-objdump used with -macho to print things 
using numeric values and not their symbolic constant names.

The routines that print Mach-O stuff already had a verbose parameter and this
change is just changing the passing true to passing !NonVerbose.  With just a
couple of fixes and a bunch of test case updates.

5109879fd6 Add code to llvm-objdump so the -section option with -macho will dump literal pointer sections 
with the Mach-O S_LITERAL_POINTERS section type.

Also fix the printing of the leading addresses for literal sections to be consistent and
not print the 0x prefix.  Updated test cases to match.

1e55a979f8 Add the -section option to llvm-objdump used with -macho that takes the argument 
segname,sectname to specify a Mach-O section to print.  The printing is based on
the section type or section attributes.

The printing of the module initialization and termination section types is printed
with this change.  Printing of other section types will be added next.

ab9fa91a6e Slightly refactor things for llvm-objdump and the -macho option so it can be used with 
options other than just -disassemble so that universal files can be used with other
options combined with -arch options.

No functional change to existing options and use.  One test case added for the
additional functionality with a universal file an a -arch option.

291f346eff Re-add support to llvm-objdump for Mach-O universal files and archives with -macho 
with fixes.  Includes the move of tests for llvm-objdump for universal files to an X86
directory.  And the fix where it was failing on linux Rafael tracked down with asan.
I had both Jim Grosbach and Adam Hemet look over the second fix since I could not
set up asan to reproduce with the old version but not with the fix.
