were lacking ExprWithCleanups nodes in some cases where the new approach to
lifetime extension needed them).
Original commit message:
Rework IR emission for lifetime-extended temporaries. Instead of trying to walk
into the expression and dig out a single lifetime-extended entity and manually
pull its cleanup outside the expression, instead keep a list of the cleanups
which we'll need to emit when we get to the end of the full-expression. Also
emit those cleanups early, as EH-only cleanups, to cover the case that the
full-expression does not terminate normally. This allows IR generation to
properly model temporary lifetime when multiple temporaries are extended by the
same declaration.
We have a pre-existing bug where an exception thrown from a temporary's
destructor does not clean up lifetime-extended temporaries created in the same
expression and extended to automatic storage duration; that is not fixed by
this patch.

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!

Next step toward supporting migrating headers. Instead of using ClangTool's
ability to override all files at once, use a custom FrontendAction and override
only the source (and eventually headers) the action is about to parse.
Use of newFrontendActionFactory() is replaced with a new factory maker provided
by Transform.

Summary:
Basically, don't special-case line comments in this regard. And fixed
an incorrect test, that relied on the wrong behavior.

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.

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.

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

Summary:
"register" functions for the checker were caching the checker objects in a
static variable. This caused problems when the function is called with a
different CheckerManager.

If you type help command <word> <word> <word> <missingSubCommand> (e.g. help script import or help type summary fake), you will get help on the deepest matched command word (i.e. script or type summary in the examples)
Also, reworked the logic for commands to produce their help to make it more object-oriented
