it to refer to castAs/getAs.
The original change to remove the (broken) cast/dyn_cast support from TypeLoc
was in r175462. (Thanks to David Blaikie for the reference.)

It looks like there is a possibility of seeing RO/RW note sections
and we would need to create an appropriate RO/RW segment associated
with them.
Adds a test too.

I tried to implement this properly in r189051, but I didn't have enough
test coverage. Richard kindly provided more test cases than I could
possibly imagine and now we should have the correct condition.

The compiler is allowed to add a linker option starting with -?<name> to
.drectve section. If the linker can interpret -<name>, it's processed as if
there's no question mark there. If not, such option is silently ignored.
This is a COFF's feature to allow the compiler to emit new linker options
while keeping compatibility with older linkers.

Before this patch, name of driver implementation is not consistent with its
option table file. Specifically, LDOptions has a different prefix than
GnuLdDriver.
This patch renames option files, so that the option files have the same prefix
as the corresponding driver files.

Instead of directly manipulating the thread list in Launch and Attach,
just rely on RefreshStateAfterStop to populate the initial list.

Original message:
If a constant or a function has linkonce_odr linkage and unnamed_addr, mark
hidden. Being linkonce_odr guarantees that it is available in every dso that
needs it. Being a constant/function with unnamed_addr guarantees that the
copies don't have to be merged.

- This aligns with how existing test suites end up wanting to use the local
config files, conceptually it makes sense to consider them to be inherited.

/bin/sh is more portable, and all systems with /bin/bash are expected to
have /bin/sh as well, even if only a link to bash.

Previously, the clang crash handling code would kick in and give a crash
report for these, even though they're not that sort of error.

This changes the interface of createLinkerInput to use ErrorOr, so that
errors from the linker can be captured.
Also adds a convenience function for error strings to be returned from
file nodes.

The reason that I am turning off this optimization is that there is an
additional case where a block can escape that has come up. Specifically, this
occurs when a block is used in a scope outside of its current scope.
This can cause a captured retainable object pointer whose life is preserved by
the objc_retainBlock to be deallocated before the block is invoked.
An example of the code needed to trigger the bug is:
----
\#import <Foundation/Foundation.h>
int main(int argc, const char * argv[]) {
void (^somethingToDoLater)();
{
NSObject *obj = [NSObject new];
somethingToDoLater = ^{
[obj self]; // Crashes here
};
}
NSLog(@"test.");
somethingToDoLater();
return 0;
}
----
In the next commit, I remove all the dead code that results from this.
Once I put in the fixing commit I will bring back the tests that I deleted in
this commit.

Summary:
Transform the token sequence for:
typename typedef T U;
to:
typename T typedef U;
Raise a diagnostic when this happens but only if we succeeded handling
the typename.
