but according to my super-optimizer there are only two missed simplifications
of -instsimplify kind when compiling bzip2, and this is one of them.  It amuses
me to have bzip2 be perfectly optimized as far as instsimplify goes!

Add C++ include paths for libstdc++ with Ubuntu 11.04 and Debian's libstdc++6-4.5, as collected from http://packages.ubuntu.com/search?mode=exactfilename&suite=natty&section=all&arch=any&searchon=contents&keywords=c%2B%2Blocale.h and http://packages.debian.org/wheezy/armel/libstdc++6-4.5-dev/filelist

This is more efficient as it's all done at once at the end of the TU.
This could still get expensive, so a flag is provided to disable it. As
an added bonus, the diagnostics will now print out a cycle.

The PCH test is XFAILed because we currently can't deal with a note
emitted in the header and I, being tired, see no other way to verify the
serialization of delegating constructors. We should probably address
this problem /somehow/ but no good solution comes to mind.

This adds functionality to remove size/zero extension during indvars
without generating a canonical IV and rewriting all IV users. It's
disabled by default so should have no effect on codegen. Work in progress.

if they're template template parameters applied to template arguments).

The basic allocator is really bad about hinting, so it doesn't eliminate all

tag, filter out those ambiguous names that we found if they aren't
within the declaration context where this newly-defined tag will be
visible.

This is basically a hack, because we really need to fix the lookup of
tag declarations in this case to not find things it
shouldn't. However, it's better than what we had before, and it fixes
<rdar://problem/9168556>.

the body of a delegating constructor call.

This means that the delegating constructor implementation should be
complete and correct, though there are some rough edges (diagnostic
quality with the cycle detection and using a deleted destructor).

LiveVariables doesn't understand that clobbering D0 and D1 completely overwrites
Q0, so if Q0 is live-in to a function, its live range will extend beyond a
function call that only clobbers D0 and D1. This shows up in the
ARM/2009-11-01-NeonMoves test case.

LiveVariables should probably implement the much stricter rules for physreg
liveness that RAFast imposes - a physreg is killed by the first use of any
alias.

Only create a canonical IV for backedge taken count if it will
actually be used by LinearFunctionTestReplace. And some related
cleanup, preparing to reduce dependence on canonical IVs.

Use a more gentle way of shutting down the child process spawned during the test execution using pexpect.
Change some child.expect() to child.expect_exact() as they try to match the string, not a regular expression.

Removed the "image" command and moved it to "target modules". Added an alias
for "image" to "target modules". 

Added some new target commands to be able to add and load modules to a target:
(lldb) target modules add <path>
(lldb) target modules load [--file <path>] [--slide <offset>] [<sect-name> <sect-load-addr> ...]

So you can load individual sections without running a target:

(lldb) target modules load --file /usr/lib/libSystem.B.dylib __TEXT 0x7fccc80000 __DATA 0x1234000000

Or you can rigidly slide an entire shared library:

(lldb) target modules load --file /usr/lib/libSystem.B.dylib --slid 0x7fccc80000

This should improve bare board debugging when symbol files need to be slid around manually.
