e2ca9e5b5f 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
not strictly legal UAL syntax. It's a common extension and the friendly
thing to do.

cef98cddbe ARM NEON relax parse time diagnostics for alignment specifiers. 
There's more variation that we need to handle. Error checking will need
to be on operand predicates.

ef70e9b704 ARM allows '' syntax, not just '#imm' for assembly. 
Backwards compatibility with 'gas'. #imm is the preferered and documented
syntax, but lots of existing code uses the '$' prefix, so we should
support it if we can.
