into separate versions for the Darwin and 64-bit SVR4 ABIs. This will
facilitate doing more major surgery on the 64-bit SVR4 ABI in the near future.

- 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.

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.

Use isa<> or cast<> when semantically that is what is happening. Also
some trivial "style" cleanups at fix sites.

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.

the rewrite visitor to make the fact that the speculation is completely
independent a bit more clear.
I promise that this is just a cut/paste of the one visitor and adding
the annonymous namespace wrappings. The diff may look completely
preposterous, it does in git for some reason.

Make sure functions located in user specified text sections (via the
section attribute) are located together with the default text sections.
Otherwise, for large object files, the relocations for call instructions
are more likely to be out of range. This becomes even more likely in the
presence of LTO.

a) frame setup instructions define the prologue
b) we shouldn't change our location mid-stream
Add a test to make sure that the stack adjustment stays within
the prologue.
