Execute's Data parameter is now optional, so we won't allocate memory
for it on Windows and we'll close the process handle.

The Unix code should probably do something similar to avoid accumulation
of zombie children that haven't been waited on.

Tested on Linux and Windows.

Now that the PRED_BAD has been removed, this is failing the Clang

This is a temporary stepping stone for moving them out of Program.

I'm taking David Blaikie's suggestion to use an
Optional<PPC::Predicate> return value instead.  That's the right
solution for this problem.  Thanks for pointing out that possibility!

Introducing PRED_BAD caused some unexpected warnings that are now
suppressed.

These records are mandatory for executables and are used by the loader.

This is a preparatory patch for fast-isel support.  The instruction
selector will need to access some functions in PPCGenCallingConv.inc,
which in turn requires several helper functions to be defined.  These
are currently defined near the only use of PCCGenCallingConv.inc,
inside PPCISelLowering.cpp.  This patch moves the declaration of the
functions into the associated header file to provide the needed
visibility.

No functional change intended.

Allows returning a PPC::Predicate from a function with a no-predicate

[MC/DWARF] Support .debug_frame / .debug_line code alignment factors

I've been comparing the object file output of LLVM's integrated
assembler against the external assembler on PowerPC, and one
area where differences still remain are in DWARF sections.

In particular, the GNU assembler generates .debug_frame and
.debug_line sections using a code alignment factor of 4, since
all PowerPC instructions have size 4 and must be aligned to a
multiple of 4.  However, current MC code hard-codes a code
alignment factor of 1.

This patch changes this by adding a "minimum instruction alignment"
data element to MCAsmInfo and using this as code alignment factor.

This requires passing a MCContext into MCDwarfLineAddr::Encode
and MCDwarfLineAddr::EncodeAdvanceLoc.  Note that one caller,
MCDwarfLineAddr::Write, didn't actually have that information
available.  However, it turns out that this routine is in fact
never used in the whole code base, so the patch simply removes
it.  If it turns out to be needed again at a later time, it
could be re-added with an updated interface.

Remove an "anchor" method for an abstract class. (This does not
increase the number of vtables.)

[PowerPC] Use assembler source in MC tests

A couple of old test cases in test/MC/PowerPC were still using
LLVM IR.  Now that we have a working assembler, we can move
them to assembler tests instead:
  ppc64-initial-cfa.ll
  ppc64-relocs-01.ll
  ppc64-tls-relocs-01.ll

This test case was a "sanity check"/"breathing" test case at first, but
is really fragile, which impairs changes to yaml2obj.

`test/Object/yaml2obj-elf-bits-endian.test` is much more robust and
serves as an adequate sanity check.

The pass emits a call to sqrt that has attribute "read-none". This call will be
converted to an ISD::FSQRT node during DAG construction, which will turn into
a mips native sqrt instruction.
