19afd91687 Solving merge issue with use of tables in dump/undump 
The use of tables in dump/undump to reuse strings did not exist in
the version that changed the representation of arrays, so it was not
corrected for the new API for tables.

7923dbbf72 Bug: Recursion in 'getobjname' can stack overflow 
'getobjname' now broken in two, a basic version that handles locals,
upvalues, and constants, and a full version, which uses the basic
version to handle table accesses (globals and fields).

81e4fce530 Simpler test in 'luaH_getint' 
The test whether key is inside the array part of a table uses a bit
trick to avoid computing the real size of the array part.

A fixed buffer keeps a binary chunk "forever", so that the program
does not need to copy some of its parts when loading it.

6b51133a98 Thread stacks resized in the atomic phase 
Although stack resize can be a little expensive, it seems unusual to
have too many threads needing resize during one GC cycle. On the other
hand, the change allows full collections to skip the propagate phase,
going straight from a pause to the atomic phase.

351ccd7332 Towards a new implementation of arrays 
The array part of a table wastes too much space, due to padding.
To avoid that, we need to store values in the array as something
different from a TValue. Therefore, the API for table access
should not assume that any value in a table lives in a *TValue.
This commit is the first step to remove that assumption: functions
luaH_get*, instead of returning a *TValue where the value lives,
receive a *TValue where to put the value being accessed.
(We still have to change the luaH_set* functions.)

09f3c2372f Option '-l' discards version sufix from file name 
Like 'require', the command-line option '-l' discards an optional
version suffix (everything after an hyphen) from a file name when
creating the module name.
