arch/tms320: pdf rendering tests for c55x and c55x+ functions

Adds full-function disassembly (pdf) tests for non-trivial functions on
both CPUs, to lock in correct rendering of basic-block boundaries,
reflines (forward and backward branches), call/data/string cross-
references and operand formatting.

C55x (emulateme_nostd.ccsv5.c55x.ticoff2.dbg.coff):
  - sym._uart_write_hex: a compact two-block function with a forward
    conditional branch, an unconditional branch refline and a call ref.
  - sym.___text: a four-block loop with conditional branches both ways,
    a back-edge, a call into another function, data references and
    parallel-instruction (||) operands.

C55x+ (coff2/19_emulateme_nostd.obj):
  - sym._c_strlen: a four-block scan loop with a back-edge and forward
    and backward bcc reflines.
  - sym._main: a five-block function with nested conditional branches
    and two call references (_c_strlen, _decrypt).

All four render cleanly with the existing decoder and analyzers; no
behavior change was needed.
