The `asm!` and `global_asm!` macros require their operands to appear strictly in the following order: - Template strings - Positional operands - Named operands - Explicit register operands - `clobber_abi` - `options` This is overly strict and can be inconvienent when building complex `asm!` statements with macros. This PR relaxes the ordering requirements as follows: - Template strings must still come before all other operands. - Positional operands must still come before named and explicit register operands. - Named and explicit register operands can be freely mixed. - `options` and `clobber_abi` can appear in any position.
