Display symbol names "compile -D"

[lpereira]

Another one in the series to improve the debuggability quality of life: display the symbol name in the "compile -D" command.

No tests seems to expect anything with the string "Disassembly of {num} bytes", so no tests have been updated.

Here's an output sample (excerpt from compile -D cranelift/filetests/filetests/wasm/f64-arith.clif):

Disassembly of 44 bytes <%f64_copysign>:
   0:	55                   	pushq	%rbp
   1:	48 89 e5             	movq	%rsp, %rbp
   4:	48 b9 00 00 00 00 00 00 00 80

  2b:	c3                   	retq

Adding the name seems like a really nice improvement, but I'm not sure about the additional hex and byte dumps, given that Capstone is already printing out the hex bytes of the instructions. Was there a specific case that you had in mind where they were improving debugging?

Rebased and force-pushed with only the change to show the function name.

Looks great, thanks!
