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

Recommit of r263252, [ELF] - Change all messages to lowercase to be consistent. which was reverted because included unrelative changes by mistake. Original commit message: [ELF] - Change all messages to lowercase to be consistent. That is directly opposite to http://reviews.llvm.org/D18045, which was reverted. This patch changes all messages to start from lowercase letter if they were not before. That is done to be consistent with clang. Differential revision: http://reviews.llvm.org/D18085 llvm-svn: 263337
