Amanieu d'Antras 52f7a218fb Relax ordering rules for asm! operands
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.
