Richard Sandiford 446067b143 [SystemZ] Tweak instruction format classifications 
There's no real need to have Shift as a separate format type from Binary.
The comments for other format types were too specific and in some cases
no longer accurate.

Just a clean-up, no behavioral change intended.

//
// These classes have the form [Cond]<Category><Format>, where <Format> is one
// of the formats defined above and where <Category> describes the inputs
// and outputs. "Cond" is used if the instruction is conditional,
// in which case the 4-bit condition-code mask is added as a final operand.
// <Category> can be one of:
//
// Inherent:
// One register output operand and no input operands.
//
// BranchUnary:
// One register output operand, one register input operand and
// one branch displacement. The instructions stores a modified
// form of the source register in the destination register and
// branches on the result.
//
// Store:
// One register or immediate input operand and one address input operand.
// The instruction stores the first operand to the address.
//
// This category is used for both pure and truncating stores.
//
// LoadMultiple:
// One address input operand and two explicit output operands.
// The instruction loads a range of registers from the address,
// with the explicit operands giving the first and last register
// to load. Other loaded registers are added as implicit definitions.
//
// StoreMultiple:
// Two explicit input register operands and an address operand.
// The instruction stores a range of registers to the address,
// with the explicit operands giving the first and last register
// to store. Other stored registers are added as implicit uses.
//
// Unary:
// One register output operand and one input operand.
//
// Binary:
// One register output operand and two input operands.
//
// Compare:
// Two input operands and an implicit CC output operand.
//
// Ternary:
// One register output operand and three input operands.
//
// LoadAndOp:
// One output operand and two input operands, one of which is an address.
// The instruction both reads from and writes to the address.
//
// CmpSwap:
// One output operand and three input operands, one of which is an address.
// The instruction both reads from and writes to the address.
//
// RotateSelect:
// One output operand and five input operands. The first two operands
// are registers and the other three are immediates.
//
// Prefetch:
// One 4-bit immediate operand and one address operand. The immediate
// operand is 1 for a load prefetch and 2 for a store prefetch.
//
// The format determines which input operands are tied to output operands,
// and also determines the shape of any address operand.
//
// Multiclasses of the form <Category><Format>Pair define two instructions,
// one with <Category><Format> and one with <Category><Format>Y. The name
// of the first instruction has no suffix, the name of the second has
// an extra "y".
