Argyrios Kyrtzidis 03535265ef Cut down unnecessary zero'ing when value-initializing arrays of C++ objects. 
-C++ objects with user-declared constructor don't need zero'ing.
-We can zero-initialize arrays of C++ objects in "bulk" now, in which case don't zero-initialize each object again.

Benjamin Kramer cf9d1ad62e We require threse bits to be zero, too. 
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.

Nick Lewycky 6aa79492a5 Only read *predecessor once so as to fix a theoretical issue where it changes 
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).

Johnny Chen fbc0d27144 Move the iteration protocol of lldb objects to the auto-generated lldb Python module. 
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()
            ....

Lenny Maiorani ed2cc6ccbb 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.

Chris Lattner 1777601a74 final step needed to resolve PR6627, which allows us to flatten the code down to 
a nice and tidy:
  %x1 = load i32* %0, align 4
  %1 = icmp eq i32 %x1, 1179403647
  br i1 %1, label %if.then, label %if.end

instead of doing lots of loads and branches.  May the FreeBSD bootloader
long fit in its allocated space.

Douglas Gregor d517d55484 When determining whether two types are reference-compatible, check 
non-CVR qualifiers as well as CVR qualifiers. For example, don't allow
a reference to an integer in address space 1 to bind to an integer in
address space 2.

Owen Anderson 715973fc6c 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.
