Add support for processing .eh_frame. This adds support for: * Uniquing CIEs * Dropping FDEs that point to dropped sections It drops 657 488 bytes from the .eh_frame of a Release+Asserts clang. The link time impact is smallish. Linking clang with a Release+Asserts lld goes from 0.488064805 seconds to 0.504763060 seconds (1.034 X slower). llvm-svn: 252790
