Includes a test case/FIXME demonstrating a bug/limitation in pointer to
member hashing. To be honest I'm not sure why we don't just always use
summary hashing for referenced types... but perhaps I'm missing
something.

This patch wasn't reviewed, and isn't correctly preserving the behaviors
relied upon by QT. I don't have a direct example of fallout, but it
should go through the standard code review process. For example, it
should never have removed the QT test case that was added when fixing
those users.

Line counts in llvm-cov are read in as 64-bit integers but were being truncated
to 32-bit in collectLineCounts(), which caused overflow for large counts.
This patch fixes all counts to be uint64_t.

This is a fix to PR17649, caused by fix in r193073. QT uses 'break' statement
to implement their 'foreach' macro. To enable build of QT, this fix reenables
break but only in 'for' statement specifier and only in the third expression.

This reverts commit r193161.
It broke
void foo() __attribute__((alias("bar")));
void bar() {}
void zed() __attribute__((alias("foo")));
Looks like we have to fix pr17639 first :-(

names. For example, with this patch we now reject
void f1(void) __attribute__((alias("g1")));
This patch is implemented in CodeGen. It is quiet a bit simpler and more
compatible with gcc than implementing it in Sema. The downside is that the
errors only fire during -emit-llvm.

If we run into the second preprocessor branch chain, the first branch
chain might have already set the maximum branch count on that level to
something > 0.
Fixes PR17645.

This patch changes two things:
a) Allow a header to be part of multiple modules. The reasoning is that
in existing codebases that have a module-like build system, the same
headers might be used in several build targets. Simple reasons might be
that they defined different classes that are declared in the same
header. Supporting a header as a part of multiple modules will make the
transistion easier for those cases. A later step in clang can then
determine whether the two modules are actually compatible and can be
merged and error out appropriately. The later check is similar to what
needs to be done for template specializations anyway.
b) Allow modules to be stored in a directory tree separate from the
headers they describe.

VTList has a long life cycle through the module and getVTList is frequently called. In current getVTList, sequential search over a std::vector is used, this is inefficient in big module.
This patch use FoldingSet to implement hashing mechanism when searching.

- Replaced tabs with proper padding
- print() takes two arguments, which are the GCNO and GCDA filenames
- Files are listed at the top of output, appended by line 0
- Stripped strings of trailing \0s
- Removed last two lines of whitespace in output

Summary:
Enforce the rule in C++11 [temp.mem]p2 that local classes cannot have
member templates.
This fixes PR16947.
N.B. C++14 has slightly different wording to afford generic lambdas
declared inside of functions.
Fun fact: Some formulations of local classes with member templates
would cause clang to crash during Itanium mangling, such as the
following:
void outer_mem() {
struct Inner {
template <typename = void>
struct InnerTemplateClass {
static void itc_mem() {}
};
};
Inner::InnerTemplateClass<>::itc_mem();
}

The manifest file is an XML file that conveys some information to the loader,
such as whether the executable needs to run as Administrator or not. This patch
is to parse command line option for manifest file.
Actual XML file generation will be done in a separate patch.

We can have a struct type with a single field and the field does not start
with 0. In that case, we should correctly update the offset.

collectLineCounts() should only organize the output data. This is done in
anticipation of subsequent changes which will pass in GCNO and GCDA filenames
into the print function where it is printed similar to the gcov output.
