[lld] size comparison script

[Rafael Espíndola via llvm-commits]

This a small script I wrote for comparing the size of two ELF binaries.

For example, this is what it prints when comparing a gold and a lld
linked clang:

.dynamic                    592      448
.dynsym                    6744     6552

.text                  41531081 41527673
.strtab                 7841007  6802265

So yes, SHF_STRING handling is next for me :-)

Cheers,
