Jim Ingham 962260c852 Fix a glitch in the Driver's batch mode when used with "attach".
Batch mode is supposed to stop execution and return control to the user when an
exceptional stop occurs (crash, signal or instrumentation).  But attach always stops
with a SIGSTOP on OSX (maybe on Linux too?) which would short circuit the rest of the
commands given.

This change allows a command result object to indicate that it expected to leave the 
process stopped with an exceptional stop reason, and it is okay for batch mode to keep going.

Dawn Perchik 954b40bf63 Add support for "source info" and use it to fix MI's -symbol-list-lines.
This patch adds support the command 'source info' as follows:
    (lldb) help source info
         Display source line information (as specified) based on the current executable's
         debug info.
    
    Syntax: source info <cmd-options>
    
    Command Options Usage:
      source info [-c <count>] [-s <shlib-name>] [-f <filename>] [-l <linenum>] [-e <linenum>]
      source info [-c <count>] [-s <shlib-name>] [-n <symbol>]
      source info [-c <count>] [-a <address-expression>]
    
           -a <address-expression> ( --address <address-expression> )
                Lookup the address and display the source information for the corresponding
                file and line.
    
           -c <count> ( --count <count> )
                The number of line entries to display.
    
           -e <linenum> ( --end-line <linenum> )
                The line number at which to stop displaying lines.
    
           -f <filename> ( --file <filename> )
                The file from which to display source.
    
           -l <linenum> ( --line <linenum> )
                The line number at which to start the displaying lines.
    
           -n <symbol> ( --name <symbol> )
                The name of a function whose source to display.
    
           -s <shlib-name> ( --shlib <shlib-name> )
                Look up the source in the given module or shared library (can be specified
                more than once).
For example:
    (lldb) source info --file x.h
    Lines for file x.h in compilation unit x.cpp in `x
    [0x0000000100000d00-0x0000000100000d10): /Users/dawn/tmp/./x.h:10
    [0x0000000100000d10-0x0000000100000d1b): /Users/dawn/tmp/./x.h:10

The new options are used to fix the MI command:
    -symbol-list-lines <file>
which didn't work for header files because it called:
    target modules dump line-table <file>
which only dumps line tables for a compilation unit.

The patch also fixes a bug in the error reporting when no files were supplied to the command. Previously you'd get:
    (lldb) target modules dump line-table
    error:
    Syntax:
    error: no source filenames matched any command arguments
Now you get:
    error: file option must be specified.

Jason Molenda 25d5b10b22 When constructing an address range to "step" or "next" through,
find the largest address range (possibly combining multiple 
LineEntry's for this line number) that is contiguous.

This allows lldb's fast-step stepping algorithm to potentially
run for a longer address range than if we have to stop at every
LineEntry indicating a subexpression in the source line.

Tamas Berghammer ccd6cffba3 Modify "platform connect" to connect to processes as well
The standard remote debugging workflow with gdb is to start the
application on the remote host under gdbserver (e.g.: gdbserver :5039
a.out) and then connect to it with gdb.

The same workflow is supported by debugserver/lldb-gdbserver with a very
similar syntax but to access all features of lldb we need to be
connected also to an lldb-platform instance running on the target.

Before this change this had to be done manually with starting a separate
lldb-platform on the target machine and then connecting to it with lldb
before connecting to the process.

This change modifies the behavior of "platform connect" with
automatically connecting to the process instance if it was started by
the remote platform. With this command replacing gdbserver in a gdb
based worflow is usually as simple as replacing the command to execute
gdbserver with executing lldb-platform.

Tamas Berghammer 4fbd67ac11 Add a new option to Platform::LoadImage to install the image
This change introduce 3 different working mode for Platform::LoadImage
depending on the file specs specified.
* If only a remote file is specified then the remote file is loaded on
  the target (same behavior as before)
* If only a local file is specified then the local file is installed to
  the current working directory and then loaded from there.
* If both local and remote file is specified then the local file is
  installed to the specified location and then loaded from there.

The same options are exposed on the SB API with a new method LoadImage
method while the old signature presers its meaning.

On the command line the installation of the shared library can be specified
with the "--install" option of "process load".

Todd Fiala 7df337f85c ArchSpec: fix unintentional promotion of unspecified unknowns to specified unknowns
* ArchSpec::MergeFrom() would erroneously promote an unspecified
  unknown to a specified unknown when both the ArchSpec and the merged
  in ArchSpec were both unspecified unknowns. This no longer happens,
  which fixes issues with global module cache lookup in some
  situations.

* Added ArchSpec::DumpTriple(Stream&) that now properly prints
  unspecified unknowns as '*' and specified unknows as 'unknown'.
  This makes it trivial to tell the difference between the two.
  Converted printing code over ot using DumpTriple() rather than
  building from scratch.

* Fixed up a couple places that were not guaranteeing that an
  unspecified unknown was recorded as such.

Currently, it only supports Objective-C - C++ types can be looked up through debug info via 'image lookup -t', whereas ObjC types via this command are looked up by runtime introspection

This behavior is in line with type lookup's behavior in Xcode 7, but I am definitely open to feedback as to what makes the most sense here
