Reid Spencer 019c8869ed For PR1146:

Anton Korobeynikov 506eaf7915 Next stage into switch lowering refactoring 
1. Fix some bugs in the jump table lowering threshold
2. Implement much better metric for optimal pivot selection
3. Tune thresholds for different lowering methods
4. Implement shift-and trick for lowering small (<machine word
length) cases with few destinations. Good testcase will follow.

Reid Spencer 52796e819f For PR1146: 
Use ParamAttrsList for writing parameter attributes. Since they are sparse
now, we also write them sparsely (saves a few bytes). Unfortunately, this
is a bytecode file format change.

Chris Lattner 7451e4d6a1 move a bunch of register constraints from being handled by 
getRegClassForInlineAsmConstraint to being handled by
getRegForInlineAsmConstraint.  This allows us to let the llvm register allocator
allocate, which gives us better code.  For example, X86/2007-01-29-InlineAsm-ir.ll
used to compile to:

_run_init_process:
        subl $4, %esp
        movl %ebx, (%esp)
        xorl %ebx, %ebx
        movl $11, %eax
        movl %ebx, %ecx
        movl %ebx, %edx
        # InlineAsm Start
        push %ebx ; movl %ebx,%ebx ; int $0x80 ; pop %ebx
        # InlineAsm End

Now we get:
_run_init_process:
        xorl %ecx, %ecx
        movl $11, %eax
        movl %ecx, %edx
        # InlineAsm Start
        push %ebx ; movl %ecx,%ebx ; int $0x80 ; pop %ebx
        # InlineAsm End

Reid Spencer bdcf9d6f08 Chris convinced me that the default size of the SmallVector (2) was too 
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.

Chris Lattner f73d215023 Fix a bug introduced with my previous patch, where it didn't correctly handle 
instructions which replace themselves when FI's are rewritten (common on ppc).
This fixes CodeGen/PowerPC/2006-10-17-ppc64-alloca.ll

Chris Lattner 4ca9cbb170 Eliminate useless insertelement instructions. This implements 
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

* Allow attributes to be added and removed singly or jointly so that in

* Move functions generally only useful for LLVM internals to the end of
  the accessors list instead of the beginning.
