7165bb8cc6 lldb: remove assertion that target_arch is FreeBSD 
The target is not necessarily a FreeBSD binary - for example, it may be
a Linux binary running under the linuxulator.  Basic ptrace (live)
debugging already worked in this case, except for the assertion.

69dcf941a4 lldb: propagate error to user if memory read fails 
Previously, an attempt to read an unreadable access reported zeros:

(lldb) memory read -format hex -size 8 0
0x00000000: 0x0000000000000000 0x0000000000000000
0x00000010: 0x0000000000000000 0x0000000000000000
...

Now, if DoReadMemory encounters error then return 0 (bytes read) so we
report the error to the user:

(lldb) memory read -format hex -size 8 0
error: Bad address

0e56f9238c For our lldb customizations, instead of commenting out lines, use #ifdef 
LLDB_ENABLE_ALL / #endif preprocess directives instead, so our diffs
against upstream only consist of added lines.

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.
