// SME Register Operands
// There are three types of SME matrix register operands:
// * Tiles:
//
// These tiles make up the larger accumulator matrix. The tile representation
// has an element type suffix, e.g. za0.b or za15.q and can be any of the
// registers:
// ZAQ0..ZAQ15
// ZAD0..ZAD7
// ZAS0..ZAS3
// ZAH0..ZAH1
// or ZAB0
//
// * Tile vectors:
//
// Their representation is similar to regular tiles, but they have an extra
// 'h' or 'v' to tell how the vector at [reg+offset] is layed out in the tile,
// horizontally or vertically.
//
// e.g. za1h.h or za15v.q, which corresponds to vectors in registers ZAH1 and
// ZAQ15, respectively. The horizontal/vertical is more a property of the
// instruction, than a property of the asm-operand itself, or its register.
// The distinction is required for the parsing/printing of the operand,
// as from a compiler's perspective, the whole tile is read/written.
//
// * Accumulator matrix:
//
// This is the entire matrix accumulator register ZA (<=> ZAB0), printed as
// 'za'.
