few comments where none existed before. Also change a function's name to match
the current coding standard.

Sean Callanan 745af46e2f Resolved two problems in the disassembler:
- Addresses with no description were given
   comments, leading to useless comments like 
   "; , "

 - Addresses weren't resolved with respect
   to the correct module.

Johnny Chen d45a9c32c2 Previous check-ins allow to hit the arm hardware watchpoint, with a workaound to handle the issue
that the inferior cannot execute past the watchpoint-triggering instruction.

The solution is disable the watchpoint before resuming the inferior and make it hardware single step;
when the inferior stops again due to single step, re-enable the watchpoint and disable the single step
to make the inferior able to continue again without obstacle.

Enrico Granata 4a3274af96 Removing cascading through inheritance chains for data formatters
This is the feature that allowed the user to have things like:

class Base { ... };
class Derived : public Base { ... };

and have formatters defined for Base work automatically for Derived.

This feature turned out to be too expensive since it requires completing types.

This patch takes care of removing cascading (other than typedefs chain cascading), updating the test suite accordingly, and adding required Cocoa class names to keep the AppKit formatters working

Chandler Carruth 13332ee518 Relax the FileCheck assertions in this test a touch. Previously the test
relied on an artifact of how the inliner and subsequent passes in
clang's -O3 mode happen to treat basic blocks and the labels for the
basic blocks. In my work on the inliner, and changed this fundamental
assumption, and the label that was being checked on the entry basic
block will no longer appear in opt builds. There was no reason to expect
the label to always be present anyways, much to my regret.

I've changed the test to just ensure that we return an immediate
constant. If there are intervening instructions, that's bad, but not
really that relevant to the test.

I'd love it if others have a better way of checking that a function body
contains only a 'ret' instruction that isn't dependent on whether or not
the entry block receives a label...

Chandler Carruth e26dafeb79 Revert a series of commits to MCJIT to get the build working in CMake
(and hopefully on Windows). The bots have been down most of the day
because of this, and it's not clear to me what all will be required to
fix it.

The commits started with r153205, then r153207, r153208, and r153221.
The first commit seems to be the real culprit, but I couldn't revert
a smaller number of patches.

When resubmitting, r153207 and r153208 should be folded into r153205,
they were simple build fixes.

Richard Smith 0b472d86de During the instantiation of a class template specialization, that
specialization is known to be incomplete. If we're asked to try to
complete it, don't attempt to instantiate it again -- that can lead
to stack overflow, and to rejects-valids if the class being incomplete
is not an error.

Greg Clayton f8712de58c Since we are having issues with the new LLVM MC disassembler, we can have
them both installed with the LLVM MC version being the default. I renamed the
name of the LLVM MC disassembler plug-in to "llvm-mc" and the LLVM enhanced
disassembly plug-in to "llvm-edis" and they can both be installed for now.

To use the "llvm-edis" disassembler, you can just specify it while disassembling:

(lldb) disassemble --plugin llvm-edis --name main
(lldb) disassemble --plugin llvm-mc --name main

This will allow us to compare the output of the two disassembler and eventually
deprecate the old one when the new one is ready. But it does use the new disassembler
by default so we continue to test it on a daily basis.

Chad Rosier 6a63a74113 [fast-isel] Fold "urem x, pow2" -> "and x, pow2-1". This should fix the 271%
execution-time regression for nsieve-bits on the ARMv7 -O0 -g nightly tester.
This may also improve compile-time on architectures that would otherwise 
generate a libcall for urem (e.g., ARM) or fall back to the DAG selector.

Johnny Chen 7cb09b61b2 WIP snapshot of hardware watchpoints for arm. A simple watchpoint has triggered.
However, the debugserver cannot get past the instruction which triggered the watchpoint.
So a workaround is in place for the time being which disables the triggered watchpoint
before resuming.

Lots of commented out printf's remain in the source which needs to be cleaned up.
