7fec90ebf4 CSE simple binary expressions when they are inserted. This makes LSR produce
less huge code that needs to be cleaned up by sdisel.

df41353497 Make sure intrinsics that are lowered to functions make the function weak
linkage so we only end up with one of them in a program. These are, after
all overloaded and templatish in nature.

69f80a63a2 Provide support for intrinsics that lower themselves to a function body.
This can happen for intrinsics that are overloaded.  In such cases it is
necessary to emit a function prototype before the body of the function
that calls the intrinsic and to ensure we don't emit it multiple times.

3a508c94a6 the result of an inline asm copy can be an arbitrary VT that the register
class supports.  In the case of vectors, this means we often get the wrong
type (e.g. we get v4f32 instead of v8i16).  Make sure to convert the vector
result to the right type.  This fixes CodeGen/X86/2007-04-11-InlineAsmVectorResult.ll

20a35c3fa5 Teach the codegen to turn [aez]ext (setcc) -> selectcc of 1/0, which often
allows other simplifications.  For example, this compiles:
int isnegative(unsigned int X) {
   return !(X < 2147483648U);
}

Into this code:

x86:
        movl 4(%esp), %eax
        shrl $31, %eax
        ret
arm:
        mov r0, r0, lsr #31
        bx lr
thumb:
        lsr r0, r0, #31
        bx lr

instead of:

x86:
        cmpl $0, 4(%esp)
        sets %al
        movzbl %al, %eax
        ret

arm:
        mov r3, #0
        cmp r0, #0
        movlt r3, #1
        mov r0, r3
        bx lr

thumb:
        mov r2, #1
        mov r1, #0
        cmp r0, #0
        blt LBB1_2      @entry
LBB1_1: @entry
        cpy r2, r1
LBB1_2: @entry
        cpy r0, r2
        bx lr
