This addresses several (not all) debug info tests that use explicit metadata
numbers. Wherever the same number appeared more than once in a test I used
a named match to ensure the same number appeared in all those cases (this may
still be overly constraining test cases as they may not have actually cared
about that relationship). For one-off numbers I just replaced them with an
unnamed regex.

This may underconstrain poorly written test cases that were interested in
checking that certain metadata nodes were related but didn't actually match
on all the related nodes numbers.

Inlining these functions is essential for correctness. We often have
cases where we do not inline calls. For example, the shallow mode and
when reanalyzing previously inlined ObjC methods as top level.

Also fixes a bug that caused us to not mark the function referenced just
because we didn't want to mark it odr used.

Different modules may have different views of the various "special"
types in the AST, such as the redefinition type for "id". Merge those
types rather than only considering the redefinition types for the
first AST file loaded.

This change introduces a 'kind' attribute for the <Para> tag, that captures the
kind of the parent block command.

For example:

\todo Meow.

used to be just <Para>Meow.</Para>, but now it is
<Para kind="todo">Meow.</Para>

With the optimization in the previous commit, this should be safe again.

Originally applied in r173951, then reverted in r174069.

This allows us to keep from chaining LazyCompoundVals in cases like this:
  CGRect r = CGRectMake(0, 0, 640, 480);
  CGRect r2 = r;
  CGRect r3 = r2;

Previously we only made this optimization if the struct did not begin with
an aggregate member, to make sure that we weren't picking up an LCV for
the first field of the struct. But since LazyCompoundVals are typed, we can
make that inference directly by comparing types.

This is a pure optimization; the test changes are to guard against possible
future regressions.

r173593 made us a little too eager to associate all code at the end of a
function with the user-written 'return' line. This caused problems with
breakpoints as they'd be set in exception handling code preceeding the
actual non-exception return handling code, leading to the breakpoint never
being hit in non-exceptional execution.

This change restores the pre-r173593 exception handling line information where
the cleanup code is associated with the '}' not the return line.

Prior to the patch, Clang does not properly promote types when a complex
integer operand is combined with an integer via a binary operator, or when
one is assigned to the other in either order.  This patch detects when
promotion is needed (and permissible) and generates the necessary code.

The test assmes no target has the same size operands for "char" and
"long long," and that no target performs arithmetic on char operands without
extending them to a larger format first.  If there are any targets for
which this is not the case, they should be XFAILed.

Introduces these negation forms explicitly and uses them to control a new
"altivec" target feature for PowerPC.  This allows avoiding generating
Altivec instructions on processors that support Altivec.

The new test case verifies that the Altivec "lvx" instruction is not
used when -fno-altivec is present on the command line.

Remove "IsMSDeclspec" argument from Align attribute since the arguments in Attr.td should

if an alignment attribute is a declspec attribute.
