bpf: New target attribute "alu32" for 32-bit subregister support
This new attribute aims to control the enablement of 32-bit subregister
support on eBPF backend.
Name the interface as "alu32" is because we in particular want to enable
the generation of BPF_ALU32 instructions by enable subregister support.
This attribute could be used in the following format with llc:
llc -mtriple=bpf -mattr=[+|-]alu32
It is disabled at default.
