Spill multiple registers at once.
...
Live range splitting can create a number of small live ranges containing only a
single real use. Spill these small live ranges along with the large range they
are connected to with copies. This enables memory operand folding and maximizes
the spill to fill distance.
Work in progress with known bugs.

That's it, I am declaring this a failure of the C++03 STL.
...
There are too many compatibility problems with using mixed types in
std::upper_bound, and I don't want to spend 110 lines of boilerplate setting up
a call to a 10-line function. Binary search is not /that/ hard to implement
correctly.
I tried terminating the binary search with a linear search, but that actually
made the algorithm slower against my expectation. Most live intervals have less
than 4 segments. The early test against endIndex() does pay, and this version is
25% faster than plain std::upper_bound().

Add a test directory stop-hook to test the newly added "target stop-hook" command.

This uses pexpect module to spawn a 'lldb' program and uses pseudo-TTY to talk to
the child application.
The test cases test setting breakpoints, adding a stop-hook with line range, and
verifies that when the inferior stops, the stop-hook will fire off when it is
within range and will not fire off when it is out of range.

Implement a hack intended to allow Clang to parse libstdc++ 4.5's
...
headers, which use C++0x generalized initializer lists. Per PR7069, it
appears that the only use is as the return type of a function, so this
commit enables this extension just in that narrow case. If it's enough
for libstdc++ 4.5, or if it can be trivially extended to work with
libstdc++ 4.5, we'll keep it. Otherwise, or if this breaks anything,
we'll revert and wait for the real feature.

Optimize trivial branches in CodeGenPrepare, which often get created from the
