BTF: fix PR debug/112768
PR debug/112768 - btf: fix asm comment output for BTF_KIND_FUNC* kinds
The patch adds a small function to abstract out the detail and return
the name of the type. The patch also fixes the issue of BTF_KIND_FUNC
appearing in the comments with a 'null' string.
For btf-function-6.c testcase, after the patch:
.long 0 # TYPE 2 BTF_KIND_FUNC_PROTO ''
.long 0xd000002 # btt_info: kind=13, kflag=0, vlen=2
.long 0x1 # btt_type: (BTF_KIND_INT 'int')
.long 0 # farg_name
.long 0x1 # farg_type: (BTF_KIND_INT 'int')
.long 0 # farg_name
.long 0x1 # farg_type: (BTF_KIND_INT 'int')
.long 0 # TYPE 3 BTF_KIND_FUNC_PROTO ''
.long 0xd000001 # btt_info: kind=13, kflag=0, vlen=1
.long 0x1 # btt_type: (BTF_KIND_INT 'int')
.long 0x68 # farg_name
.long 0x1 # farg_type: (BTF_KIND_INT 'int')
.long 0x5 # TYPE 4 BTF_KIND_FUNC 'extfunc'
.long 0xc000002 # btt_info: kind=12, kflag=0, linkage=2
.long 0x2 # btt_type: (BTF_KIND_FUNC_PROTO '')
.long 0xd # TYPE 5 BTF_KIND_FUNC 'foo'
.long 0xc000001 # btt_info: kind=12, kflag=0, linkage=1
.long 0x3 # btt_type: (BTF_KIND_FUNC_PROTO '')
