c3384c93c0 ARM Refactor VLD/VST spaced pair instructions. 
Use the new composite physical registers.

28f08c93e7 ARM refactor away a bunch of VLD/VST pseudo instructions. 
With the new composite physical registers to represent arbitrary pairs
of DPR registers, we don't need the pseudo-registers anymore. Get rid of
a bunch of them that use DPR register pairs and just use the real
instructions directly instead.

51222d1551 NEON use vmov.i32 to splat some f32 values into vectors. 
For bit patterns that aren't representable using the 8-bit floating point
representation for vmov.f32, but are representable via vmov.i32, treat
the .f32 syntax as an alias. Most importantly, this covers the case
'vmov.f32 Vd, #0.0'.

2dd674fdce Removing unused default switch cases in switches over enums that already account for all enumeration values explicitly. 
(This time I believe I've checked all the -Wreturn-type warnings from GCC & added the couple of llvm_unreachables necessary to silence them. If I've missed any, I'll happily fix them as soon as I know about them)

allow it to look ahead and grab the symbol from the next non-whitespace
line.

04b5d93250 ARM assembly shifts by zero should be plain 'mov' instructions. 
"mov r1, r2, lsl #0" should assemble as "mov r1, r2" even though it's

thing to do.
