35e01ed21d Small improvements in 'lmem.c' 
Added some auxiliary macros + fixed a bug in compilation option
EMERGENCYGCTESTS. (It should not try to force an emergency collection
when it cannot run one.)

1537d6680b New control for reentrancy of emergency collections 
Instead of assuming that shrinking a block may be an emergency
collection, use an explicit field ('gcstopem') to stop emergency
collections while GC is working.

59c88f846d Broadening the use of branch hints 
More uses of macros 'likely'/'unlikely' (renamed to
'l_likely'/'l_unlikely'), both in range (extended to the
libraries) and in scope (extended to hooks, stack growth).

56ec432281 Change in macro HARDMEMTESTS for testing GC 
Macro HARDMEMTESTS broke in two: HARDMEMTESTS forces a full GC cycle
at every point where the GC can run. New macro EMERGENCYGCTESTS
forces an emergency collection at every memory allocation.

9cdf6b7082 Some details in 'lmem.c' and 'lgc.c' 
- Several new comments in 'lmem.c'.
- Both 'luaM_growaux_' and 'luaM_shrinkvector_' use 'luaM_saferealloc_'
  to check for errors. Moreover, the use of 'luaM_saferealloc_' makes
  'luaM_shrinkvector_' try again if shrink fails (which can happen now).
- In 'checkSizes', save old debt only when needed.

d36a31e673 Reviving HARDMEMTESTS 
This commit brings a new implementation for HARDMEMTESTS, which forces
an emergency GC whenever possible. It also fixes some issues detected
with this option:
  - A small bug in lvm.c: a closure could be collected by an emergency
  GC while being initialized.
  - Some tests: a memory address can be immediatly reused after a GC;
  for instance, two consecutive '{}' expressions can return exactly the
  same address, if the first one is not anchored.

c5ebed7399 'luaM_shrinkvector' raises an error if it cannot shrink the block 
(several parts of Lua use array size in protos as proxies for
number of valid elements)

e663a24ab0 more freedom in handling memory-allocation errors (not all allocations 
automatically raise an error), which allows fixing a bug when resizing
a table.

bb4baa73ea allocation function is not exactly API (and cannot raise errors 
like other API functions); better not use 'api_check' for cheking it.
