0fa4377182 Upgrade our copies of clang, llvm, lldb and compiler-rt to r311606 from 
the upstream release_50 branch.

As of this version, lib/msun's trig test should also work correctly
again (see bug 220989 for more information).

4c320ca0d6 lldb: Report inferior signals as signals, not exceptions, on FreeBSD 
This is the FreeBSD equivalent of LLVM r238549.

This serves 2 purposes:

* LLDB should handle inferior process signals SIGSEGV/SIGILL/SIGBUS/
  SIGFPE the way it is suppose to be handled. Prior to this fix these
  signals will neither create a coredump, nor exit from the debugger
  or work for signal handling scenario.
* eInvalidCrashReason need not report "unknown crash reason" if we have
  a valid si_signo

39901227a5 lldb: Make i386-*-freebsd expression work on JIT path 
* Enable i386 ABI creation for freebsd
* Added an extra argument in ABISysV_i386::PrepareTrivialCall for mmap
  syscall
* Unlike linux, the last argument of mmap is actually 64-bit(off_t).
  This requires us to push an additional word for the higher order bits.
* Prior to this change, ktrace dump will show mmap failures due to
  invalid argument coming from the 6th mmap argument.

b08e22797d lldb: map TRAP_CAP to a trace trap 
In the absense of a more specific handler for TRAP_CAP (generated by
ENOTCAPABLE or ECAPMODE while in capability mode) treat it as a trace
trap.

Example usage (testing the bug in PR219173):

% proccontrol -m trapcap lldb usr.bin/hexdump/obj/hexdump -- -Cv -s 1 /bin/ls
...
(lldb) run
Process 12980 launching
Process 12980 launched: '.../usr.bin/hexdump/obj/hexdump' (x86_64)
Process 12980 stopped
* thread #1, stop reason = trace
    frame #0: 0x0000004b80c65f1a libc.so.7`__sys_lseek + 10
...

In the future we should have LLDB control the trapcap procctl itself
(as it does with ASLR), as well as report a specific stop reason.
This change eliminates an assertion failure from LLDB for now.

28ae63f991 For lldb, delete the custom Xcode-only Host/Config.h, and provide a 
pre-generated version in lib/clang/include/lldb/Host instead, similar to
what we do for clang, llvm and lld.

b1eb23b26b Don't adjust the program counter to an invalid address after reaching a 
breakpoint. The value doesn't need to be adjusted as it is already
correctly returned from the kernel.

This allows lldb to set breakpoints, and stop on them, however more work
is needed, for example single stepping fails to stop.
