detected in the forward-CFG DFS. This prevents the reverse-CFG from
visiting blocks inside loops after blocks that dominate them in the
case where loops have multiple exits.

No testcase, because this fixes a bug which in practice only shows
up in a full optimizer run, due to the use-list order.

This fixes rdar://10422791 and others.

We will return a valid range when possible and omit the "permissions" key
when the memory is not readable, writeable or executeable. This will help us
know the difference between an error back from this packet and unsupported,
from just "this address isn't in a valid region".

Downgrade the alignment of the initial constant island when constant

This is all gated by -arm-align-constant-islands.

Support/FileSystem: Implement canonicalize.

As an extension, support incomplete types in the unordered containers to match what we already do in the associative containers.

llvm-svn: 146376

Order constant pool entries by descending alignment in the initial
island to ensure packing and correct alignment.  When the command line
flag is set, also align the basic block containing the constant pool
entries.

This is only a partial implementation of constant island alignment. More
to come.

CMake versions 2.8.4 and earlier were giving this error since r146323:
"string end index: -1 is out of range 0 - 6"

Passing -1 as the length of the desired substring was a new feature
added in CMake 2.8.5:

I followed three heuristics for deciding whether to set 'true' or
'false':

- Everything target independent got 'true' as that is the expected
  common output of the GCC builtins.
- If the target arch only has one way of implementing this operation,
  set the flag in the way that exercises the most of codegen. For most
  architectures this is also the likely path from a GCC builtin, with
  'true' being set. It will (eventually) require lowering away that
  difference, and then lowering to the architecture's operation.
- Otherwise, set the flag differently dependending on which target
  operation should be tested.

Let me know if anyone has any issue with this pattern or would like
specific tests of another form. This should allow the x86 codegen to
just iteratively improve as I teach the backend how to differentiate
between the two forms, and everything else should remain exactly the
same.

intrinsic syntax.

Now that this is explicitly covered, I plan to upgrade the existing test
suite to use an explicit immediate. Note that I plan to specify 'true'
in most places rather than the auto-upgraded value as that is the far
more common value to end up here as that is the value coming from GCC's
builtins. The only place I'm likely to put a 'false' in is when testing
x86 which actually has different instructions for the two variants.
