cf08915d62 New macro LUA_USE_IOS 
Do not try to detect automatically whether system is iOS; it is
simpler and more reliable to let the programmer inform that.

c888ae0aea Small changes in hash of pointers 
When converting from pointer to integer, use 'uintptr_t' if available;
otherwise try 'uintmax_t', and use 'size_t' as last resource.

d69789da1c Fix absence of 'system' in iOS

does not implement 'system'.

8dea54877a Do not avoid major collections when GCdebt is zero 
'collectgarbage("step")' (without an argument) does not have any
special meaning, it means "do a step with some default size".

314745ed84 Avoid excessive name pollution in test files 
Test files are more polite regarding the use of globals when locals
would do, and when globals are necessary deleting them after use.

7d4c7ae2af Changes in opcodes for generic 'for' 
Again, as the control variable is read only, the code doesn't need
to keep an internal copy of it.

d70a0c91ad Dump/undump reuse strings

occurence, instead of another copy of the string.

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.)

debt for next step also is always the same.

152b51955a Removed GC checks from function calls 
Function calls do not create new objects. (It may use memory with
stack reallocation, but now that is irrelevant to the GC.)

9ede317c70 Threads are created like other objects 
Using a version of 'luaC_newobj' that allows offsets (extra space
before the object itself).

8047b2d03e Tables have a 'lastfree' information only when needed 
Only tables with some minimum number of entries in their hash part
have a 'lastfree' field, kept in a header before the node vector.

ee645472eb Stack reallocation done with a single realloc 
To avoid the need of both the old and the new stack addresses valid
at the same time, to correct the pointers to the stack, these pointers
are changed to offsets before the reallocation and then changed back
to pointers after the reallocation.

413a393e62 Stack indices changed to union's 
That will allow to change pointers to offsets while reallocating
the stack.

cfbe378f90 Small simplification in overflow check in 'getfield' 
Subtracting a small non-negative int from a non-negative int cannot
overflow, and adding a non-negative int to INT_MIN cannot overflow.
