James Lyon 41b3c7a507 Improved variable length array support. 
VLA storage is now freed when it goes out of scope. This makes it
possible to use a VLA inside a loop without consuming an unlimited
amount of memory.

Combining VLAs with alloca() should work as in GCC - when a VLA is
freed, memory allocated by alloca() after the VLA was created is also
freed. There are some exceptions to this rule when using goto: if a VLA
is in scope at the goto, jumping to a label will reset the stack pointer
to where it was immediately after the last VLA was created prior to the
label, or to what it was before the first VLA was created if the label
is outside the scope of any VLA. This means that in some cases combining
alloca() and VLAs will free alloca() memory where GCC would not.

James Lyon ae2ece93da Fixed i386 calling convention issue and CMake build on i386. 
The i386 calling convention expects the callee to pop 1 word of the
stack when performing a struct ret.

James Lyon 2bbfaf436f Tests in abitest.c now work on Win32. 
I expect that Linux-x86 is probably fine. All other architectures
except ARM are definitely broken since I haven't yet implemented
gfunc_sret for these, although replicating the current behaviour
should be straightforward.

Kirill Smelkov ab24aaeca3 i386: We can change 'lea 0(%ebp),r' to 'mov %ebp,r' 
Because that mov is 1 byte shorter, look:

    int *func()
    {
        return __builtin_frame_address(0);
    }

before patch:

00000000 <func>:
   0:   55                      push   %ebp
   1:   89 e5                   mov    %esp,%ebp
   3:   81 ec 00 00 00 00       sub    $0x0,%esp
   9:   8d 45 00                lea    0x0(%ebp),%eax   // <- here
   c:   e9 00 00 00 00          jmp    11 <func+0x11>
  11:   c9                      leave
  12:   c3                      ret

after patch:

00000000 <func>:
   0:   55                      push   %ebp
   1:   89 e5                   mov    %esp,%ebp
   3:   81 ec 00 00 00 00       sub    $0x0,%esp
   9:   89 e8                   mov    %ebp,%eax        // <- here
   b:   e9 00 00 00 00          jmp    10 <func+0x10>
  10:   c9                      leave
  11:   c3                      ret
