b74ed07bfd Adding dllimport, dllexport and external weak linkage types. 
DLL* linkages got full (I hope) codegeneration support in C & both x86
assembler backends.
External weak linkage added for future use, we don't provide any
codegeneration, etc. support for it.

0f27fc34f7 Fix a regression in the 32-bit port from the 64-bit port landing. 
We now compile CodeGen/X86/lea-2.ll into:

_test:
        movl 4(%esp), %eax
        movl 8(%esp), %ecx
        leal -5(%ecx,%eax,4), %eax
        ret

instead of:

_test:
        movl 4(%esp), %eax
        leal (,%eax,4), %eax
        addl 8(%esp), %eax
        addl $4294967291, %eax
        ret
