In the SelectionDAG immediate operands to inline asm are constructed as
two separate operands. The first is a constant of value InlineAsm::Kind_Imm
and the second is a constant with the value of the immediate.
In ARMDAGToDAGISel::SelectInlineAsm, if we reach an operand of Kind_Imm we
should skip over the next operand too.

This is a better implementation of r183097. The main purpose is to
prevent certain constructs to be formatted "like a block of text".
Before:
aaaaaaaaaaaaa<
aaaaaaaaaa, aaaaaaaaaaa, aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa,
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa>* aaaa = new aaaaaaaaaaaaa<
aaaaaaaaaa, aaaaaaaaaaa, aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa,
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa>(bbbbbbbbbbbbbbbbbbbbbbbb);
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa[
bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb] = (*cccccccccccccccc)[
dddddddddddddddddddddddddddddddddddddddddddddddddddddddd];
After:
aaaaaaaaaaaaa<aaaaaaaaaa, aaaaaaaaaaa,
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa,
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa>* aaaa =
new aaaaaaaaaaaaa<aaaaaaaaaa, aaaaaaaaaaa,
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa,
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa>(
bbbbbbbbbbbbbbbbbbbbbbbb);
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa[
bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb] =
(*cccccccccccccccc)[
dddddddddddddddddddddddddddddddddddddddddddddddddddddddd];

Additionally, allow breaking after c-style casts, but with a high
penalty.
Before:
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa *foo = (
aaaaaaaaaaaaaaaaa *)bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb;
After:
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa *foo = (aaaaaaaaaaaaaaaaa *)
bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb;
This fixes llvm.org/PR16049.

Now the two possible uses of not are
* not cmd
Will return true if cmd doesn't crash and returns false.
* not --crash cmd
Will return true if cmd crashes.
It will be used/tested in a followup commit for the clang crash recovery
testing.

We were being a bit too aggresive here in classifying global variables
with no global reference or constant value to be invalid - this would
cause LLVM to not emit the DWARF description of the global variable if
it had been optimized away, which isn't helpful for users who might
benefit from the global variable's description even if there's no
location information.
This also fixes a crasher issue here that I was unable to reduce a test
case for - involving a using decl (& subsequent
DW_TAG_imported_declaration ) of such a global variable that, once
optimized away, would crash when an attempt to emit the imported
declaration was made.

r179494 switched to using the object file info to retrieve the default text
section for some MC streamers. It is possible that initializing an MC
streamer can request sections before the object file info is initialized
when the AutoInitSections flag is set on the streamer.

This transform was originally added in r185257 but later removed in
r185415. The original transform would create instructions speculatively
and then discard them if the speculation was proved incorrect. This has
been replaced with a scheme that splits the transform into two parts:
preflight and fold. While we preflight, we build up fold actions that
inform the folding stage on how to act.

This implements a proper PPCAsmBackend::writeNopData routine
that actually writes PowerPC nop instructions.
This fixes the last remaining difference in object file output
(text section) between the integrated assembler and GNU as
that I've seen anywhere.

* all transforms are in the same category
* all transforms' options are in the same category
* display the CommonOptionParser extra-help (which describe in more details the
compilation database stuff)
* add EXAMPLES section

Some versions of python will expand the glob used in the test, others wont,
causing the test to fail when run with LIT_USE_INTERNAL_SHELL=1.

This adds a new decoder table/namespace 'VFPV8', as these instructions have their
top 4 bits as 0b1111, while other Thumb instructions have 0b1110.
