Summary: This patch adds syntax highlighting support to LLDB. When enabled (and lldb is allowed to use colors), printed source code is annotated with the ANSI color escape sequences. So far we have only one highlighter which is based on Clang and is responsible for all languages that are supported by Clang. It essentially just runs the raw lexer over the input and then surrounds the specific tokens with the configured escape sequences.
