Reasons:
* We disabled it more than a year ago for all configs
* Not easy to re-enable
* Not compatible with pointer compression as-is
* Not compatible with concurrent TP/TF as-is
* No concrete plans to re-enable it
Also remove Map's layout_descriptor since it was only used for double
field unboxing.

Currently, it can be little difficult to understand why a command in
lldb-commands.py stops working. For example, at the moment running the
jlh command results in an empty line:
$ lldb --one-line "command script import ../../tools/lldb_commands.py" \
v8_hello_world
(lldb) br s -f hello-world.cc -l 49
(lldb) jlh script
(lldb)
With this commit this would instead display the following error message:
(lldb) jlh script
Failed to evaluate command
_v8_internal_Print_Object(*(v8::internal::Object**)(*(void*)(script))) :
error: cannot cast from type 'v8::Local<v8::Script>' to pointer type
'void *'
The output is really only two lines but I've wrapped the lines here so
they don't exceed the 72 column width. I'll follow up with a commit to
fix the issue reported.

of Python 2(aka _legacy_ Python) https://pythonclock.org/ .
The code compatibility check for python2 and python3
used the following tools: futurize, flake8

The goal of this commit is to add the equivalent to gdbinit but
for lldb. I've tried to replicate the commands as close as possible
but I'm unsure about the jss command and hoping to get some feedback
on it in addition to the bta command which I'm not sure how/when this
could be used. This is probably just inexperience on my part.
The lldbinit file can be placed into a directory prefixed with dot
(.lldbinit) and the python script is currently expected to be in the
same directory. The path to the script can be changed manually if needed
as well.
