This shouldn't happen in practice because the icmp would be a constant.
Add a check so we don't miscompile code if something goes wrong.

between two reads (threading).

Fix an off-by-one in the indirect counter table that I meant to revert after an
earlier experiment. Whoops!

Implement GCOV_PREFIX. Doesn't handle GCOV_PREFIX_STRIP yet.

Fix an off-by-one in string emission. Extra whoops!

Tolerate DISubprograms that have null Function*'s attached to them. I don't yet
understand what this means, but it happens when you have a global static with
a non-trivial constructor/destructor.

Fix a crash on switch statements with a single successor (default-only).

This is so that the objects which support the iteration protocol are immediately obvious
from looking at the lldb.py file.

SBTarget supports two types of iterations: module and breakpoint.  For an SBTarget instance,
you will need to issue either:

    for m in target.module_iter()

or

    for b in target.breakpoint_iter()

For other single iteration protocol objects, just use, for example:

    for thread in process:
        ID = thread.GetThreadID()
        for frame in thread:
            frame.Disassemble()
            ....

Enhance clang_getCXTUResourceUsage() to report how much memory is used by SourceManager's memory buffers.

Add MemoryBuffer::getBufferKind() to report whether a memory buffer uses malloc'ed or mmap'ed memory.  This is for performance analysis.

Remove bounded StringRef::compare() since nothing but Clang SA was using it and it is just as easy to use StringRef::substr() preceding StringRef::compare() to achieve the same thing.

Use StringRef::substr() and unbounded StringRef::compare() instead of bounded version of StringRef::compare() because bounded version of StringRef::compare() is going to be removed.

Eliminates an assert in the strncpy/strncat checker caused by not validating a cast was successful. If the value of an argument was unknown, the cast would result in a NULL pointer which was later being dereferenced.

This fixes Bugzilla #9806.

Fix a bug in tblgen that caused incorrect encodings on instructions that specified operands with "bit" instead of "bits<1>".
Unfortunately, my only testcase for this is fragile, and the ARM AsmParser can't round trip the instruction in question.
