Mach-O files don’t have size information about the symbols in the object file
format unlike ELF.
Also add the part of the fix to llvm-nm that was missed with r290001 so
-arch armv7m works.

This patch fixes a small bug where symbols defined in the INIT
and FINI sections were incorrectly getting a type of 'n'.

Undefined and weak symbols don't have a meaningful size or value.
As such, nothing should be printed for those attributes (this is
already done for the address with 'U') with the BSD format. This
matches what GNU nm does.
Note that for the POSIX.2 format [1] zero values are still
printed for the size and value. This seems in spirit with
the format strings in that specification, but is debatable.

This is where an LC_SEGMENT load command has a fileoff field that
extends past the end of the file.
Also fix llvm-nm and llvm-size to remove the errorToErrorCode() call so error messages are printed.
And needed to update a few test cases now that they do print the error messages just a
bit differently.

1) For Mach-O files the code was not printing the values in hex as is the default.
2) The values printed had leading zeros which they should not have.
3) The address for undefined symbols was printed as spaces instead of 0.
4) With the -A option with posix output for an archive did not use square
brackets around the archive member name.

We already perform it at the beginning of the function so we can't
arrive here with an invalid object. Also, add a test so that bugs
won't sneak in the future.

Which is needed if we want to replace darwin’s nm(1) with llvm-nm
as there are many uses of grouped flags. The added test case is
one specific case that is in real use.

While llvm-nm parses the -g option and has help that describes it as:
-extern-only - Show only external symbols
There is no code in the program to use the boolean valve it sets from the
command line.
