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

9527c4949f i386: fix loading of LLOCAL floats 
These loads clobbered ebx as TinyCC wanted to load the address into st0.

1308e8ebcf integrate x86_64-asm.c into i386-asm.c 
Also, disable 16bit support for now as it causes bugs
in 32bit mode.  #define I386_ASM_16 if you want it.

5dadff3de5 x86-64: Fix stab debug information. 
We need 32bit relocations for code and 64bit for debug info.
Introduce a new macro R_DATA_PTR to distinguish the two usages.
