00001c: 01 c0 add %eax,%eax

However, this could be two instructions.

The function was also moved to the header so that it could be inlined at
the two call sites. Without this, 32-bit also needs to pull the
parameter from the stack. This means there is a push, a call, a move,
and a ret added to a two instruction function. The above code shows the
function with __attribute__((regparm=1)), but even this adds several
extra instructions. There is also an extra instruction on 64-bit to
move the parameter to %eax for the subtract.

i965/miptree_map_blit: Don't do the initial copy if INVALIDATE_RANGE is set
Before we were always coping from the buffer being mapped into the
temporary buffer. However, if INVALIDATE_RANGE is set, then we know that
the data is going to be junk after we unmap so there's no point in doing
the blit. This is important because doing the blit will cause a stall 3
lines later when we map the buffer.

i965/fs: Allow constant propagation between different types
This will be needed for NIR because it is typeless and treats all constants
as uint32 values and reinterprets them when they are used later. This
commit allows those values to be properly propagated.
Also, this helps some synmark shaders because it allows us to copy
propagate a 0x00000000UD into a 0.0F in a load_payload, which then lets us
combine 4 load_payloads.
