This fixes PR28326.

Passing -output-dir path/to/dir to llvm-cov show creates path/to/dir if
it doesn't already exist, and prints reports into that directory.

In function view mode, all views are written into
path/to/dir/functions.$EXTENSION. In file view mode, all views are
written into path/to/dir/coverage/$PATH.$EXTENSION.

Changes since the initial commit:

- Avoid accidentally closing stdout twice.

It is only used internally by the ScopInfo pass. By moving it into its
own header file we avoid it being processed that use only ScopInfo.

The methods in ScopBuilder are used for the construction of a Scop,
while the remaining classes of ScopInfo are required by all passes that
use Polly's polyhedral analysis.

llvm-svn: 273982

This function is used by both ScopInfo and ScopBuilder. A common
location for this function is required when ScopInfo and ScopBuilder are
separated into separate files in the next commit.

This was producing acceses to registers beyond the super
register's limits, resulting in verifier failures.

DiagnosticNoteRenderer asserts trying to emit its "while building
module Foo imported from bar.h:5" note when the presumed location
of the import is invalid. This assertion was added in r267914,
where most uses of 'getFilename' were updated to test 'isValid'
instead. This one must have been missed.

I can't come up with a test because this location is always valid
in C-based code, but external clients that manually import modules
(*cough*Swift*cough*) sometimes provide invalid SourceLocations.

Wanted this when writing tests for the proposed CG update stuff, and
this is an easily separable piece.

Fixup the "shadow" example command to use the function that takes an execution context now that the @lldb.command decorator does the right thing for the command function that takes 5 arguments.

A few fixes:
- Check the process state to make sure it is stopped
- Grab the frame from the "exe_ctx" so this will work during breakpoint callbacks
- Print out the SBDeclaration objects of the variables that shadow each other so we can see the source locations of which variable declarations are shodowing each other.

the new pass manager.

This adds operator<< overloads for the various bits of the
LazyCallGraph, dump methods for use from the debugger, and debug logging
using them to the CGSCC pass manager.

Having this was essential for debugging the call graph update patch, and
I've extracted what I could from that patch here to minimize the delta.

Target::Install() was assuming the module at index 0 was the executable.
This is often true, but not guaranteed to be the case.  The
TestInferiorChanged.py test highlighted this when run against iOS.
After the binary is replaced in the middle of the test, it becomes the
last module in the list.  The rest of the Target::Install() logic then
clobbers the executable file by using whatever happens to be the first
module in the target module list.

This change also marks the TestInferiorChanged.py test as a no-debug-info
test.

Apparently, MSVC complains if there's an implicit conversion from
`unsigned` to `unsigned long long`, if the `unsigned` is the result of
a bit shift.

explicit in how it adds the kernel binary, to guard against the
case where a kernel corefile might incorrectly include the kernel's
UUID in it (so calling ::GetSharedModule may end up returning the
global module cache's copy of the core file instead of adding the
kerenl binary).
