When building an AST file, we don't want to output HeaderFileInfo
structures for files that are not actually used as headers in the
current context. This can lead to assuming that unrelated files have
include counts of 0, defeating multiple-include prevention.
This is accomplished by adding an IsValid bit to the HFI.

This was leading to bad formatting, e.g.:
Before:
f(^{
@autoreleasepool {
if (a) {
g();
}
}
});
After:
f(^{
@autoreleasepool {
if (a) {
g();
}
}
});

const-qualified parameter type and the defined with a non-const-qualified
parameter type, the parameter is not const inside its body. Ensure that
the type we use when instantiating the body is the right one. Patch by
suyog sarda!
This is still rather unsatisfactory; it seems like it might be better to
instantiate at least the function parameters, and maybe the complete function
declaration, when we instantiate the definition for such a member function
(instead of reusing the declaration from inside the instantiated class
definition).

that implicitly converts to 'bool' (such as pointers, and the first operand of
?:). Clean up issues found by this. Patch by Stephan Tolksdorf!

They're already defined in ia32intrin.h, and this would cause including Intrin.h
in 64-bit mode to fail because of conflicting types. Update ms-intrin.cpp to
also run in 64-bit mode to catch things like this.

This updates CodeGenPGO to use the ProfileDataReader introduced to
llvm in r203703 and the new API for writing out the profile introduced
to compiler-rt in r203710.

When a struct has bitfields overlapping with other members
(as required by the AAPCS), clang uses a packed struct to
represent this. If such a struct is large enough for clang to
pass it as a byval pointer (>64 bytes), we need to set the
alignment of the argument to match the original type.

When enabled, always validate the system headers when loading a module.
The end result of this is that when these headers change, we will notice
and rebuild the module.

Normalise the path separator character on non-windows platforms. Although this
would work on Windows as well (most newer versions of Windows support either '/'
or '\' as a path separator character), it could potentially cause problems with
full UNC paths. This change enables the use of the Windows SDK on Linux which
will not accept '\' as a path separator.

PGO counters are 64-bit and branch weights are 32-bit. Scale them down
when necessary, instead of just taking the lower 32 bits.

Like the binary operator check of r201702, this actually checks the
condition of every if in a chain against every other condition, an
O(N^2) operation. In most cases N should be small enough to make this
practical, and checking all cases like this makes it much more likely
to catch a copy-paste error within the same series of branches.

Someone could write:
if (0) {
__c11_atomic_load(ptr, memory_order_release);
}
or the equivalent, which is perfectly valid, so we shouldn't outright reject
invalid orderings on purely static grounds.
