gdb: Avoid warning for the jump command inside an inline function.

Browse Source 
When stopped inside an inline function, trying to jump to a different line
of the same function currently results in a warning about jumping to another
function.  Fix this by taking inline functions into account.

Before:
  Breakpoint 1, function_inline (x=510) at jump-inline.cpp:22
  22        a = a + x;             /* inline-funct */
  (gdb) j 21
  Line 21 is not in `function_inline(int)'.  Jump anyway? (y or n)

After:
  Breakpoint 2, function_inline (x=510) at jump-inline.cpp:22
  22        a = a + x;            /* inline-funct */
  (gdb) j 21
  Continuing at 0x400679.

  Breakpoint 1, function_inline (x=510) at jump-inline.cpp:21
  21        a += 1020 + a;                /* increment-funct */

This was regression-tested on X86-64 Linux.
