/// This file implements the instruction info view.
///
/// The goal fo the instruction info view is to print the latency and reciprocal
/// throughput information for every instruction in the input sequence.
/// This section also reports extra information related to the number of micro
/// opcodes, and opcode properties (i.e. 'MayLoad', 'MayStore', 'HasSideEffects)
///
/// Example:
///
/// Instruction Info:
/// [1]: #uOps
/// [2]: Latency
/// [3]: RThroughput
/// [4]: MayLoad
/// [5]: MayStore
/// [6]: HasSideEffects
///
/// [1]    [2]    [3]    [4]    [5]    [6]	Instructions:
///  1      2     1.00                    	vmulps	%xmm0, %xmm1, %xmm2
///  1      3     1.00                    	vhaddps	%xmm2, %xmm2, %xmm3
///  1      3     1.00                    	vhaddps	%xmm3, %xmm3, %xmm4
