more instances now and we're sending extra memory reads resulting
in a performance degredation while stepping.

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.

GDB MI allows for this and it is necessary if the variable name contains spaces, such as var5.std::_Vector_base<std::basic_string<char, std::char_traits<char>, std::allocator<char> >, std::allocator<std::basic_string<char, std::char_traits<char>, std::allocator<cahr> > > >.

Summary:
As per the following link, the "--" separator can appear between the options
and parameters of any MI command. Previously this separator was only
handled by the `-data-disassemble` MI command. I have moved the relevant
code into `CMICmdBase` so that any MI command can handle the
aforementioned separator.

Summary:
I observed that eclipse was passing --thread-group for many other commands
then we are currently handling. Looking at the MI documentation, the
following link states that each MI command accept the --thread and
--frame option. Looking at the GDB implementation, it seems that apart
from these 2, --thread-group is also handled the same way.
https://sourceware.org/gdb/onlinedocs/gdb/Context-management.html#Context-management
So instead of handling those arguments in every comamnds, I have moved
them into the base class and removed them from elsewhere. Now any command
can use these arguments. The patch seems big but most of the changes are
mechanical.

A variable of type:
struct S {
union {
int i1;
unsigned u1;
};
union {
int i2;
unsigned u2;
};
};
had been impossible to evaluate in lldb-mi, because MI assigns '??' as the
variable name to each of the unnamed unions after "-var-list-children" command.
Also '??' incorrectly goes to 'exp' field which is treated by IDE as a
structure field name and is displayed in watch window.
The patch fixes this returning empty string as type name for unnamed union and
assigning $N to variable name, where N is the field number in the parent entity.

Ingham added support for a new SPI needed to request app launches

Previously, lldb did not use type summaries for simple types with no children

In r248047, I attempted to fix a build breakage introduced by using
llvm's regex support from lldb-mi. However, my approach was flawed
when LLVM and lldb are dynamically linked, in which case two copies
of LLVMSupport would end up in memory, causing crashes on lldb start up.
Instead, use LINK_COMPONENTS to make sure lldb-mi has access to the
LLVMSupport symbols without causing duplication in the dynamic library
case.

Summary:
This is Darwin only.
The symbol defined by ${LLDB_VERS_GENERATED_FILE} is used by
source/lldb.cpp, so anything that uses lldb.cpp (which is in
lldbBase) should also have the generated symbol. This means
that the entire process can be centralized within source/CMakeLists.txt
where lldbBase is constructed.
Additionally, the custom command should have dependencies on the
project file as well as the generation script so that if either
changes, the version file is correctly re-generated and everything
is re-linked appropriately.
* cmake/LLDBDependencies.cmake: Remove everything related to
the generated version file from here.
* source/CMakeLists.txt: On Darwin, add the generated version
file to the sources that make up lldbBase. Also, create a
custom target and make lldbBase depend on it to re-generate
the generated file as needed.
* source/API/CMakeLists.txt: Don't need to build the generated
version file here or use it to control linking against swig_wrapper.
* tools/lldb-server/CMakeLists.txt: Likewise.

If a string contained characters outside the ASCII range, lldb-mi would
print them as hexadecimal codes. This patch fixes this behaviour by
converting to UTF-8 instead, by having lldb-mi use registered type
summary providers, when they are available. This patch also fixes
incorrect evaluation of some composite types, like std::string, by
having them use a type registered type summary provider.

This patch adds a --start option to the lldb-mi -exec-run command for
getting process stopped at entry point after launch. It is equivelent
to the -s option in the lldb command line interpreter:
process launch -s
and is therefore not supported on all hosts and/or targets. To check
if the --start option is supported, see if the corresponding feature
"exec-run-start-option" is in the list of options reported by the lldb-mi
"-list-features" command.

debugserver to match. "gcc" is now "ehframe" and "gdb" is now
"debugserver". Because this is debugserver, what we call the Process
Plugin register numbers up in lldb are the debugserver register
numbers down here - they are the register numbers that debugserver
will use to refer to these registers over the gdb-remote protocol.
debugserver was already reporting the registers with the key
"ehframe"; this change is just cleaning up the internal variable
names to match.
