+Add IR op metadata tags in json
+Initial Metadata:

+

+- StoreMemory

+  - Stores to memory. Ensures that even if the op doesn't generate output, that it can't be DCE'd

+- Volatile

+  - Similar to StoreMemory. Even if it doesn't write memory, this is a volatile op that shouldn't be DCE'd

+

+Architecture specific select of metadata

+- ClobbersFlags

+  - Clobbers host side flags, so if FLAG register class is used, must be spilled around this op

+- NecessaryTemps

+  - Number of temp registers this IR op needs to work. Will allocate a register that its live range starts at this op and then ends at the same op

+- PhysicalRegisters - (We need both dest physical colouring and argument physical colouring)

+  - If this op needs specific physical registers then this is an RA constraint that enforces those registers to be allocated
