[llvm-readobj]Add testing for ELF symbol and section table printing for a wider range of values
The existing ELF symbol and section table testing doesn't test many of the corner-cases or valid values for various ELF properties, including things like binding, visibility, section type and so on. This patch adds a series of tests that test these and other related edge-cases. Reviewed by: grimar, MaskRay Differential Revision: https://reviews.llvm.org/D58457 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@354577 91177308-0d34-0410-b5e6-96231b3b80d8
