When the scheduler unfold a load folding instruction it move some of the predecessors to the unfolded load. It decides what gets moved to the load by checking whether the new load is using the predecessor as an operand. The check neglects the cases whether the predecessor is a flagged scheduling unit.

An empty global constant (one of size 0) may have a section immediately
...
following it. However, the EmitGlobalConstant method wasn't emitting a body for
the constant. The assembler doesn't like that. Before, we were generating this:
.zerofill __DATA, __common, __cmd, 1, 3
This fix puts us back to that semantic.

Target independent isel should always pass along the "tail call" property. Change
target hook LowerCall's parameter "isTailCall" into a refernce. If the target
decides it's impossible to honor the tail call request, it should set isTailCall
to false to make target independent isel happy.

Rearrange handling of jump tables. Highlights:
...
1. MachineJumpTableInfo is now created lazily for a function the first time
it actually makes a jump table instead of for every function.
2. The encoding of jump table entries is now described by the
MachineJumpTableInfo::JTEntryKind enum. This enum is determined by the
TLI::getJumpTableEncoding() hook, instead of by lots of code scattered
throughout the compiler that "knows" that jump table entries are always
32-bits in pic mode (for example).
3. The size and alignment of jump table entries is now calculated based on
their kind, instead of at machinefunction creation time.
Future work includes using the EntryKind in more places in the compiler,
eliminating other logic that "knows" the layout of jump tables in various
situations.

For blocks that are not loop headers, just print their loop depth and header BB.
...
For loop headers, print Inner loop along with the other stuff so it doesn't take
an extra line. We now get stuff like this:
LBB1_4: ## %land.end
## in Loop: Header=BB1_1 Depth=1
notb %al
testb $1, %al
jne LBB1_8
and:
LBB1_6: ## %while.cond7
## Inner Loop Header: Depth=3
## Inside Loop BB1_5 Depth 2
## Inside Loop BB1_1 Depth 1
which still isn't great for loop headers, but is much less verbose.

missing ones are libsupport, libsystem and libvmcore. libvmcore is
