NEON vector types need to be mangled in a special way to comply with ARM's ABI,
similar to some of the AltiVec-specific vector types.  This patch is mostly
just renaming a bunch of "AltiVecSpecific" things, since they will no longer
be specific to AltiVec.  Besides that, it just adds the new "NeonVector" enum.

references. For example, this allows gvn to eliminate the load in
this example:

  void foo(int n, int* p, int *q) {
    p[0] = 0;
    p[1] = 1;
    if (n) {
      *q = p[0];
    }

in the order they occur within the class template, delaying
out-of-line member template partial specializations until after the
class has been fully instantiated. This fixes a regression introduced
by r118454 (itself a fix for PR8001).

Whenever splitting wants to insert a copy, it checks if the value can be
rematerialized cheaply instead.

Missing features:
- Delete instructions when all uses have been rematerialized.
- Truncate live ranges to the remaining uses after rematerialization.

nodes can be used in loops, this could result in infinite looping
if there is no recursion limit, so add such a limit.  It is also
used for the SelectInst case because in theory there could be an
infinite loop there too if the basic block is unreachable.

The simplifications performed here never create new instructions, they
only return existing instructions (or a constant), and so are always a
win.  In theory they should transform (for example)
  %z = and i32 %x, %y
  %s = select i1 %cond, i32 %y, i32 %z
  %r = and i32 %x, %s
into
  %r = and i32 %x, y
but in practice they get into a fight with instcombine, and lose.
Unfortunately instcombine does a poor job in this case.  Nonetheless
I'm committing this transform to make it easier to discuss what to
do to make peace with instcombine.

Win32/Process.inc: [PR8527] Process::FileDescriptorIsDisplayed(fd) should not check by FILE_TYPE_CHAR. It must be better to check it with Console API.

The special file "NUL" is FILE_TYPE_CHAR with GetFileType(h). It was treated as display device and discarding output to NUL had failed. (eg. opt -o nul)
