gas: scfi: replace verbose expressions with local vars

Replace the scattered and repeated uses of verbose expressions with
variables.  E.g.,
  ginsn_get_src_reg (src1)  -> src1_reg
  ginsn_get_src_type (src1) -> src1_type
etc.

This hopefully makes the logic bit more maintainable.  While at it,
include minor adjustments to make few checks in gen_scfi_ops () more
precise:
  - When getting imm value from src operand, ensure the src type is
    GINSN_SRC_IMM,
  - When getting reg from src operand, ensure the src type is checked
    too (GINSN_SRC_REG or GINSN_SRC_INDIRECT as appropriate).

On the other hand, the changes in verify_heuristic_traceable_reg_fp ()
and verify_heuristic_traceable_stack_manipulation () are purely
mechanical.

gas/
        * scfi.c (verify_heuristic_traceable_reg_fp): Add new local
	vars and reuse them.
        (verify_heuristic_traceable_stack_manipulation): Likewise.
        (gen_scfi_ops): Likewise.  Additionally, make some conditionals
	more precise.
