Jordan Rupprecht 4888c4aba5 [llvm-size][libobject] Add explicit "inTextSegment" methods similar to "isText" section methods to calculate size correctly. 
Summary:
llvm-size uses "isText()" etc. which seem to indicate whether the section contains code-like things, not whether or not it will actually go in the text segment when in a fully linked executable.

The unit test added (elf-sizes.test) shows some types of sections that cause discrepencies versus the GNU size tool. llvm-size is not correctly reporting sizes of things mapping to text/data segments, at least for ELF files.

This fixes pr38723.

Jordan Rupprecht 8d60f9b6d2 [llvm-size] Berkeley formatting: use tabs instead of spaces as field delimeters. 
This matches GNU behavior for size and allows use of cut to parse the output of llvm-size.

Kevin Enderby 600fb3f28e Add the first of what will be a long line of additional error checks for invalid Mach-O files. 
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.

Rafael Espindola a0ff556aa1 This brings back commit r259578. 
But now it follows the llvm style, uses an early return and doesn't
include a file named 1.o.

Rafael Espindola 77f6c46922 Revert "Correct size calculations for ELF files" 
This reverts commit r259578.

There are enough issues with this small patch that it is better to
revert and then commit a fixed version (will be committed shortly).

Kevin Enderby 2058e9dff0 Fix a formatting problems with llvm-size and the -m option. 
It was using format() with a string for 64-bit types but was
passed a 32-bit type in places when printing values for
32-bit Mach-O files.
