that if we prefer the current compile unit, followed by any compile units that
already had their DIEs parsed, followed by the rest of the matches, that we
might save some memory. This turned out not to help much. The code is commented
out, but I want to check it in so I don't lose the code in case it could help
later.
Added the ability to efficiently find the objective C class implementation
when using the new .apple_types acclerator tables with the type flags. If the
type flags are not available, we default back to what we were doing before.

Patch by Brendon Cahoon!
This extends the existing LoopUnroll and LoopUnrollPass. Brendon
measured no regressions in the llvm test suite with -unroll-runtime
enabled. This implementation works by using the existing loop
unrolling code to unroll the loop by a power-of-two (default 8). It
generates an if-then-else sequence of code prior to the loop to
execute the extra iterations before entering the unrolled loop.

that got hit, and first check the condition, and if that location's condition says we should stop, then we
run the callback. In the end if any location's condition and callback say we should stop, then we stop.

documentation) with one based on what GCC's __builtin_constant_p is actually
intended to do (discovered by asking a friendly GCC developer).
In particular, an expression which folds to a pointer is now only considered to
be a "constant" by this builtin if it refers to the first character in a string
literal.
This fixes a rather subtle wrong-code issue when building with glibc. Given:
const char cs[4] = "abcd";
int f(const char *p) { return strncmp(p, cs, 4); }
... the macro magic for strncmp produces a (potentially crashing) call to
strlen(cs), because it expands to an expression starting with:
__builtin_constant_p(cs) && strlen(cs) < 4 ? /* ... */
Under the secret true meaning of __builtin_constant_p, this is guaranteed to be
safe!

all of the headers below that particular directory. Use umbrella
directories as a clean way to deal with (1) directories/frameworks
that don't have an umbrella header, but don't want to enumerate all of
their headers, and (2) PrivateHeaders, which we never want to
enumerate and want to keep separate from the main umbrella header.
This also eliminates a little more of the "magic" for private headers,
and frameworks in general.

translation unit has a interface for a class "Bar" that contains hidden ivars
in the implementation and we make sure we can see these hidden ivars. We also
test the case where we stop in translation unit that contains the
implementation first. So the test runs two tests:
1 - run and stop where we have an interface, run to main and print and make
sure we find the hidden ivar
2 - run and stop where we have an implementation, run to main and print and make
sure we find the hidden ivar

establish a firm layering separation between these two libraries.

in the context in which it was originally found, the
expression parser now goes hunting for it in all modules
(in the appropriate namespace, if applicable). This means
that forward-declared types that exist in another shared
library will now be resolved correctly.
Added a test case to cover this. The test case also tests
"frame variable," which does not have this functionality
yet.
