parse just a single declaration and provide a reasonable diagnostic
when the "only one declarator per template declaration" rule is
violated. This eliminates some ugly, ugly hackery where we used to
require thatn the layout of a DeclGroup of a single element be the
same as the layout of a single declaration.

to allow us to support generation of deferred ctors/dtors.
It looks like codegen isn't emitting a call to the dtor in
member-functions.cpp:test2, but when it does, its body should
get emitted.

functions and methods declared inline, but not ctors/dtors or methods not declared
inline (apparently my previous patch wasn't good enough).

Per the FIXME, it might be interesting to track whether the inline keyword
was also used on the method, but for now we don't do this. Testcase pending.

- moved shrink wrapping code from PrologEpilogInserter.cpp to
new file ShrinkWrapping.cpp.
- moved PEI pass definition into new shared header PEI.h.

array region, set its default value to conjured symbol. When retrieving its
element, create new region value symbol for the element.
Also fix some 80 columns violations.

- This matches the normal dependency generation code.
- This also fixes the problem that when building a normal and bitcode
archive from the same source, the dependency files would overwrite
one another. Which was bad.

after finding the (unique) layout predecessor. Sometimes a block may be listed
more than once, and processing it more than once in this loop can lead to
inconsistent values for FtTBB/FtFBB, since the AnalyzeBranch method does not
clear these values. There's no point in continuing the loop regardless.
The testcase for this is reduced from the 2003-05-02-DependentPHI SingleSource
test.

and generalize it so that it can be used by IndVarSimplify. Implement the
base IndVarSimplify transformation code using IVUsers. This removes
TestOrigIVForWrap and associated code, as ScalarEvolution now has enough
builtin overflow detection and folding logic to handle all the same cases,
and more. Run "opt -iv-users -analyze -disable-output" on your favorite
loop for an example of what IVUsers does.
This lets IndVarSimplify eliminate IV casts and compute trip counts in
more cases. Also, this happens to finally fix the remaining testcases
in PR1301.
Now that IndVarSimplify is being more aggressive, it occasionally runs
into the problem where ScalarEvolutionExpander's code for avoiding
duplicate expansions makes it difficult to ensure that all expanded
instructions dominate all the instructions that will use them. As a
temporary measure, IndVarSimplify now uses a FixUsesBeforeDefs function
to fix up instructions inserted by SCEVExpander. Fortunately, this code
is contained, and can be easily removed once a more comprehensive
solution is available.

These values aren't analyzable, so they don't care if more information
about the loop trip count can be had. Also, SCEVUnknown is used for
a PHI while the PHI itself is being analyzed, so it needs to be left
in the Scalars map. This fixes a variety of subtle issues.

return the correct value when the cast operand is all zeros. This ought
to be pretty rare, because it would mean that the regular SCEV folding
routines missed a case, though there are cases they might legitimately
miss. Also, it's unlikely anything currently using GetMinTrailingZeros
cares about this case.

TemplateArgumentList. This avoids the need to pass around
pointer/length pairs of template arguments lists, and will eventually
make it easier to introduce member templates and variadic templates.
