[PATCH 2/4] elflint, readelf, support SHT_LLVM_LTO and SHT_LLVM_ADDRSIG

[Mark Wielaard]

An SHT_LLVM_LTO section contains LLVM bitcode. An SHT_LLVM_ADDRSIG
section contains ULEB128 integers referring to the symbol table
indexes of address-significant symbols. This patch just recognizes the
SHT constants but doesn't handle the section contents.

         * libebl/eblsectiontypename.c (ebl_section_type_name):
         Recognize SHT_LLVM_ADDRSIG and SHT_LLVM_LTO.
