tracing/kprobes: Add bitfield type
Add bitfield type for tracing arguments on kprobe-tracer. The syntax of
a bitfield type is:
b<bit-size>@<bit-offset>/<container-size>
e.g.
Accessing 2 bits-width field with 4 bits-offset in 32 bits-width data at
4 bytes offseted from the address pointed by AX register:
+4(%ax):b2@4/32
Since the width of container data depends on the arch, so I just added
the container-size at the end.
