8e59e163db do not share old induction variables when this would result in invalid
instructions (that would have to be split later)

64c88d741e bugfix: When the source register of CALL_NOLINK was LR, the following code was emitted:
mov lr, pc
    bx lr
So, the function was not called.

a16b7cb1d3 Two changes:
1) codegen a shift of a register as a shift, not an LEA.
2) teach the RA to convert a shift to an LEA instruction if it wants something
   in three-address form.

This gives us asm diffs like:

-       leal (,%eax,4), %eax
+       shll $2, %eax

which is faster on some processors and smaller on all of them.

and, more interestingly:

-       movl 24(%esi), %eax
-       leal (,%eax,4), %edi
+       movl 24(%esi), %edi
+       shll $2, %edi

Without #2, #1 was a significant pessimization in some cases.

This implements CodeGen/X86/shift-codegen.ll
