As part of our overall switch from hand-rolling RTTI to using LLVM-compatible
methods, I've done the same for ExpressionVariable.  The main documentation for
how to do this is in TypeSystem.h, so I've simply referred to that.

This change extends the bitset lowering pass to support bitsets that may
contain either functions or global variables. A function bitset is lowered to
a jump table that is laid out before one of the functions in the bitset.

Also add support for non-string bitset identifier names. This allows for
distinct metadata nodes to stand in for names with internal linkage,
as done in D11857.

  While we do not need to model PHI nodes in the region exit (as it is not part
  of the SCoP), we need to prepare for the case that the exit block is split in
  code generation to create a single exiting block. If this will happen, hence
  if the region did not have a single exiting block before, we will model the
  operands of the PHI nodes as escaping scalars in the SCoP.

Summary:
Add a test for a data followed by 4-byte hash value.
I use a slightly modified Jenkins hash function,
as described in https://en.wikipedia.org/wiki/Jenkins_hash_function

The modification is to ensure that hash(zeros) != 0.

Summary: This patch modifies X86TargetLowering::LowerVASTART so that
struct va_list is initialized with 32 bit pointers in x32. It also
includes tests that call @llvm.va_start() for x32.

These were marked as WriteSALU, which is low latency.
I'm guessing at the value to use, but it should probably
be considered the highest latency instruction.

I'm not sure this has any actual effect since hasSideEffects
probably is preventing any moving of these.

This should be convergent. This is not a

The old implementation assumed LP64 which is broken for x32.  Specifically, the

Instead of having two separate options
-polly-detect-scops-in-functions-without-loops and

This corner case happens when we have an irreducible SCC that is
deeply nested.  As we work down the tree, the backedge masses start
getting smaller and smaller until we reach one that is down to 0.

Since we distribute the incoming mass using the backedge masses as
weight, the distributor does not allow zero weights.  So, we simply
ignore them (which will just use the weights of the non-zero nodes).
