add a version of createLowerInvokePass that allows the client
to specify whether it wants "expensive" or "cheap" lowering.

otherwise labels get incorrectly merged. We handled this by emitting a
".byte 0", but this isn't correct on thumb/arm targets where the text segment
needs to be a multiple of 2/4 bytes. Handle this by emitting a noop. This
is more gross than it should be because arm/ppc are not fully mc'ized yet.
This fixes rdar://7908505

doesn't dominate the header is needed, don't check whether the increment
expression has computable loop evolution. While the operands of an
addrec are required to be loop-invariant, they're not required to
dominate any part of the loop. This fixes PR6914.

alignment of globals with a specified alignment, we fix
common variables to obey their alignment. Add a comment
explaining why this behavior is important.

form of DEBUG_VALUE, as it doesn't have reasonable default
behavior for unsupported targets. Add a new hook instead.
No functional change.

Also, generalize ScalarEvolutions's min and max recognition to handle
some new forms of min and max that this change makes more common.

to use this new utility routine soon.

alignment to match what's used in clang and GCC for __alignof, rather
than trying to guess what Legalize is going to be doing.

This fixes a bug where calls inlined into an invoke would get
changed into an invoke but the array would keep pointing to
the (now dead) call. The improved inliner behavior is still
disabled for now.

Add the instruction pointer value for debuggability.
We now get dump output that looks like this:
Call graph node for function: 'f1'<<0x1017086b0>> #uses=1
CS<0x1017046f8> calls external node
Call graph node for function: '_ZNSt6vectorIdSaIdEEC1EmRKdRKS0_'<<0x1017086f0>> #uses=1
CS<0x0> calls external node
Call graph node for function: 'f4'<<0x1017087a0>> #uses=1
CS<0x101708c88> calls function 'f3'

misses an opportunity to fold add operands, but folds them
after LSR has separated them out. This fixes rdar://7886751.

that appear in the SCC as a result of inlining as candidates
for inlining. Change this so that it *does* consider call
sites that change from being indirect to being direct as a
result of inlining. This allows it to completely
"devirtualize" the testcase.
