small.  Since it doesn't cost much to have 2 more (8 bytes), but not having
them would require a malloc as soon as the third one is needed. Setting
the default to 4 delays the malloc until the 5th parameter attribute.

instructions which replace themselves when FI's are rewritten (common on ppc).
This fixes CodeGen/PowerPC/2006-10-17-ppc64-alloca.ll

Transforms/InstCombine/vec_insertelt.ll and fixes PR1286.

We now compile the code from that bug into:

_foo:
        movl 4(%esp), %eax
        movdqa (%eax), %xmm0
        movl 8(%esp), %ecx
        psllw (%ecx), %xmm0
        movdqa %xmm0, (%eax)
        ret

instead of:

_foo:
        subl $4, %esp
        movl %ebp, (%esp)
        movl %esp, %ebp
        movl 12(%ebp), %eax
        movdqa (%eax), %xmm0
        #IMPLICIT_DEF %eax
        pinsrw $2, %eax, %xmm0
        xorl %ecx, %ecx
        pinsrw $3, %ecx, %xmm0
        pinsrw $4, %eax, %xmm0
        pinsrw $5, %ecx, %xmm0
        pinsrw $6, %eax, %xmm0
        pinsrw $7, %ecx, %xmm0
        movl 8(%ebp), %eax
        movdqa (%eax), %xmm1
        psllw %xmm0, %xmm1
        movdqa %xmm1, (%eax)
        movl %ebp, %esp
        popl %ebp
        ret

woo :)

some instructions can have multiple frame indices in them.  If this happens,
rewrite all of them.

* Allow attributes to be added and removed singly or jointly so that in
  the future something like -pruneh can manipulate them more easily.
* Move functions generally only useful for LLVM internals to the end of
  the accessors list instead of the beginning.
