This commits implements size classes in the GC for the Variable Width
Allocation feature. Unless `USE_RVARGC` compile flag is set, only a
single size class is created, maintaining current behaviour. See the
redmine ticket for more details.

This commit removes T_PAYLOAD since the new VWA implementation no longer
requires T_PAYLOAD types.

rather than having to do this in a two step process:
1. heap_page obj
2. dump_page $2 (or whatever lldb variable heap_page set)
we can now just
dump_page_rvalue obj
Update the lldb script so it can mostly recover a Ruby stack trace from
a core file. It's still missing line numbers and dealing with CFUNCs,
but you use it like this:
```

Getting the main execution context is difficult (it is stored in a
thread local) so for now you must supply an ec and this will make a
backtrace
Show the size of String.
To see the whole contents even after NUL char:
```
(lldb) rp str
(const char [5]) $1 = "x"
(lldb) memory read -s1 --format x --count `sizeof($1)` -- &$1 0x1010457a8: 0x78 0x00 0x61 0x61 0x61
```
The outputs from HandleCommand are printed immediately before print
statements. Fix the order in `result` by capturing the outputs.

retry loading the infos when needed.
