Jim Ingham a7d4822c75 Refine the fix in r187094 to only distrust the StackID comparision when we are starting from an address with no symbols.
If we don't do that "nexti" will stop too soon when stepping past a tail call jump.

Sean Callanan 4d682d25fb Fixed several problems with watchpoint expressions.
- First, the watchpoint size was being cast to the
  wrong type.  This is primarily cosmetic, but
  annoying.

- Second, the options for the watchpoint command
  were not being initialized correctly, which led
  to the watchpoint size sometimes having absurdly
  large values.  This caused watchpoints to fail to
  be set in some cases.

Ed Maste 4d90f0f2c3 Fix test execution on FreeBSD versions other than 9.x
The tests use a plugin based on the name from sys.platform.
Unfortunately that string includes the major version number in
Python 2.7, so the tests would look for builder_freebsd9.py,
builder_freebsd10.py, etc.

The issue doesn't affect Linux as Python returns 'linux2' also
on Linux 3.x -- see http://bugs.python.org/issue12326 for details.

It seems later versions of Python will drop the major version
number, so adopt this convention now for FreeBSD.

Jim Ingham 886a3e2cdf Handle the case where we are stepping through code with no symbols, so we can't really find the function start PC
and so the StackID changes with every step.  Do so by checking the parent frame ID, and if it hasn't changed,
then we haven't stepped in.

Stefanus Du Toit fc6b7a0e8a Remove builtin attribute from calls whose targets we replace
If we are replacing a function with the nobuiltin attribute, it may be called
with the builtin attribute on call sites. Remove any such attributes since it's
illegal to have a builtin call to something other than a nobuiltin function.

This fixes the current buildbot breakage (where LLDB crashes on
"expression new foo(42)").

Ed Maste 76859d6cb2 elf-core: Parse vendor-specific notes
ELF notes contain a 'name' field, which specifies a vendor who defines
the format of the note.  Examples are 'FreeBSD' or 'GNU', or it may be
empty for generic notes.

Add a case for FreeBSD-specific notes, leaving Linux and GNU notes,
other vendor-specific notes, and generic notes to be handled by the
existing code for now.

Thanks to Samuel Jacob for reviewing and suggesting improvements.

Stefanus Du Toit 403477bdac Remove spurious "-C" flag from CMake command lines in build.html.
-C usually specifies a script to prepopulate the CMake cache. In this case no
script is specified, so CMake appears to just ignore it. So don't mention it
in the first place - it's not desired anyways.

Ed Maste 7d6753738a elf-core: Run-time reg context selection
Instantiate RegisterContextCore... based on getOS() instead of with
compile-time #ifdef-ery.

The assert()s here are unfortunate, but better than crashing with no
explanation.  (This would previously happen for an unsupported
architecture, anyhow.)

We should add an equivalent OS and architecture test to
ProcessElfCore::DoLoadCore() and cleanly report the error to the user.

On FreeBSD I see that Arch, Vendor, OS, and Environment are unchanged

If we need to restore it we should be able to switch on
arch.GetTriple.getOS() instead of a compile-time #ifdef.
