Found that having a method to check the strucutre of the followon graph makes
it easy to debug file readers. The method checks if there's no wrong edge in
followOnNexts and followOnRoots. It is called only when debuggging is enabled
for LayoutPass.

Option: -mllvm -warn-stack-size=<limit>
Output (if limit is exceeded):
warning: Stack size limit exceeded (<actual size>) in <functionName>.
The longer term plan is to hook that to a clang warning.

My recent ARM FastISel patch exposed this bug:
http://llvm.org/bugs/show_bug.cgi?id=16178
The root cause is that it can't select integer sext/zext pre-ARMv6 and
asserts out.
The current integer sext/zext code doesn't handle other cases gracefully
either, so this patch makes it handle all sext and zext from i1/i8/i16
to i8/i16/i32, with and without ARMv6, both in Thumb and ARM mode. This
should fix the bug as well as make FastISel faster because it bails to
SelectionDAG less often. See fastisel-ext.patch for this.
fastisel-ext-tests.patch changes current tests to always use reg-imm AND
for 8-bit zext instead of UXTB. This simplifies code since it is
supported on ARMv4t and later, and at least on A15 both should perform
exactly the same (both have exec 1 uop 1, type I).
2013-05-31-char-shift-crash.ll is a bitcode version of the above bug
16178 repro.
fast-isel-ext.ll tests all sext/zext combinations that ARM FastISel
should now handle.
Note that my ARM FastISel enabling patch was reverted due to a separate
failure when dealing with MCJIT, I'll fix this second failure and then
turn FastISel on again for non-iOS ARM targets.
I've tested "make check-all" on my x86 box, and "lnt test-suite" on A15
hardware.

Reworked the download information on lldb.llvm.org:
- svn copy of download.html to source.html with information on source-code access
- new download.html with links to download nightly builds and Debian releases
- updated the sidebar to reflect these changes

Fix an assertion when the compiler encounters big constants whose bit width is
not a multiple of 64-bits.
Although clang would never generate something like this, the backend should be
able to handle any legal IR.

OpenBSD's stack smashing protection differs slightly from other
platforms:
1. The smash handler function is "__stack_smash_handler(const char
*funcname)" instead of "__stack_chk_fail(void)".
2. There's a hidden "long __guard_local" object that gets linked
into each executable and DSO.
Patch by Matthew Dempsky.
llvm-svn: 183533
Summary:
Introduced two new style parameters: PenaltyBreakComment and
PenaltyBreakString. Add penalty for each character of a breakable token beyond
the column limit (this relates mainly to comments, as they are broken only on
whitespace). Tuned PenaltyBreakComment to prefer comment breaking over breaking
inside most binary expressions.
Fixed a bug that prevented *, & and && from being considered TT_BinaryOperator
in the presense of adjacent comments.
