Document "f <n>" selects frame n.
"t <n>" selects thread n but this was just added to TOT
so most people won't have access to an lldb that accepts it.

- Substitute hyphen to underscore, s/-/_/g, as the variable name.
- Additional parameter can be specified as the name of directory.
e.g.) add_llvm_external_project(clang-tools-extra extra)
- LLVM_EXTERNAL_CLANG_TOOLS_EXTRA_SOURCE_DIR=/path/to/llvm-srcroot/tools/clang/tools/extra, by default.
- Build directory is in ${CMAKE_CURRENT_BINARY_DIR}/extra

have an alloca or a parameter, since then the alloca test should make sense
to readers, while before it probably appears too specific. No functionality
change.

The internal representation of the Attributes class will be opaque. All of the
query methods will need to query the opaque class. Therefore, these methods need
to be out-of-line.
No functionality change intended.

It is now a regex command alias that more faithfully emulates gdb's
behavior, most importantly, "bt 5" will backtrace 5 frames of the
currently selected thread. "bt all" still backtraces all threads
(unlike gdb) and for users who have learned to use "bt -c 5", that
form is still accepted.

often hear feedback from people that having the lldb commands on
the left hand side is non-intuitive -- they say "I want a *gdb* to
*lldb* table, not a *lldb* to *gdb* table". It doesn't seem odious
to go from the right-hand column to the left hand column but I've
heard this same feedback enough that it's also pointless to keep
the format lldb-first, gdb-second when it was an arbitrary choice
to begin with.

This document describes how to set up LLVM-style RTTI for a class
hierarchy. Surprisingly, this was not previously documented.
Also, link it into ProgrammersManual.html.

This is a mechanical change of dynamic_cast<> to dyn_cast<>. A number of
these uses are actually more like isa<> or cast<>, and will be changed
to the semanticaly appropriate one in a future patch.

are in fact identity operations. We detect these and kill their
partitions so that even splitting is unaffected by them. This is
particularly important because Clang relies on emitting identity memcpy
operations for struct copies, and these fold away to constants very
often after inlining.
Fixes the last big performance FIXME I have on my plate.
