df01610d6f Re-encoded 128-bit AVX versions of SQRT, RSQRT, RCP have 3 operands 
instead of 2. They were already defined this way in their regular
version, but not for the intrinsics versions (*_Int), and that would work
for assembly emission but not for object code, since a MachineOperand
would be missing. This commit fix PR10697.

Also removed the {VSQRT,VRSQRT,VRCP}r_Int forms and match the intrinsic
via INSERT_SUBREG+EXTRACT_SUBREG patterns. The same couldn't be done for
memory versions because sse_load_f32/sse_load_f64 operand need special
handling and don't work like regular "addr" operands.

There are right now 114 "*_Int" and 98 "Int_*" forms! I'm slowly
removing them as I step through, but hope we can get rid of these
someday, they are really annoying :)

90b5a08e1f ARM Thumb blx instruction fixup has same data range as bl. 
These fixups are handled poorly in general, and should have a single
contiguous range of bits per fixup type, but that's not how they're
currently organized, so for now in complex ones like for blx, we just tell the
emitter it's OK for the fixup to munge any bit it wants.

70939ee141 ARM clean up the imm_sr operand class representation.

0e6d230abd Introduce matching patterns for vbroadcast AVX instruction. The idea is to 
match splats in the form (splat (scalar_to_vector (load ...))) whenever
the load can be folded. All the logic and instruction emission is
working but because of PR8156, there are no ways to match loads, cause
they can never be folded for splats. Thus, the tests are XFAILed, but
I've tested and exercised all the logic using a relaxed version for
checking the foldable loads, as if the bug was already fixed. This
should work out of the box once PR8156 gets fixed since MayFoldLoad will
work as expected.
