[docs] Convert remaining command guide entries from md to rst.

Summary:
Linking between markdown and rst files is currently not supported very well, e.g. the current llvm-addr2line docs [1] link to "llvm-symbolizer" instead of "llvm-symbolizer.html". This is weirdly broken in different ways depending on which versions of sphinx and recommonmark are being used, so workaround the bug by using rst everywhere.

+llvm-addr2line - a drop-in replacement for addr2line
+====================================================
+
+.. program:: llvm-addr2line
+
+SYNOPSIS
+--------
+
+:program:`llvm-addr2line` [*options*]
+
+DESCRIPTION
+-----------
+
+:program:`llvm-addr2line` is an alias for the :manpage:`llvm-symbolizer(1)`
+tool with different defaults. The goal is to make it a drop-in replacement for
+GNU's :program:`addr2line`.
+
+Here are some of those differences:
+
+-  Defaults not to print function names. Use `-f`_ to enable that.
+
+-  Defaults not to demangle function names. Use `-C`_ to switch the
+   demangling on.
+
+-  Defaults not to print inlined frames. Use `-i`_ to show inlined
+   frames for a source code location in an inlined function.
+
+-  Uses `--output-style=GNU`_ by default.
