The output is as follows:
qemu-system-x86_64 -cpu help | grep "\["
x86 Cascadelake-Server-v2  Intel Xeon Processor (Cascadelake) 
[ARCH_CAPABILITIES]
x86 Cascadelake-Server-v3  Intel Xeon Processor (Cascadelake) 
[ARCH_CAPABILITIES, no TSX]
x86 Denverton-v2          Intel Atom Processor (Denverton) [no MPX, no MONITOR]
x86 Icelake-Client-v2     Intel Core Processor (Icelake) [no TSX]
x86 Icelake-Server-v2     Intel Xeon Processor (Icelake) [no TSX]

Changes in v3:
     - Keep the existing custom model-id (Eduardo)

Changes in v2:
     - correct the note of Cascadelake v3 (Xiaoyao)
