Extended Description

I get stuff like:

JIT: Stub emitted at [0x7087fd8] for function 'test'
JIT: Finished CodeGen of [0x7088028] Function: main: 88 bytes of text, 9 relocations
Disassembled code:
No disassembler available. See configure help for avaiable options.
JIT: Lazily resolving function 'test' In stub ptr = 0x7087ff0 actual ptr = 0x7087fd8
JIT: Finished CodeGen of [0x7088090] Function: test: 12 bytes of text, 0 relocations
Disassembled code:
No disassembler available. See configure help for avaiable options.

It would be much better if the "Disassembled code/No disassembler available" lines just were not
printed on targets without a disassembler.

Currently we're supporting only udis86 library for x86-{32,64} code. So, I
assume, that this message should be printed in case of any other target. Right?

s/should/shouldn't

[lattner]

Right. I would suggest that libsystem export a "hasDisassembler()" function. If this returns false, the JIT
should not attempt to disassemble the produced code.
