  [FastIsel][X86] Fix invalid register replacement for bool args

   %4 = trunc i8 %3 to i1
   %5 = call %jl_value_t.0* @foo(..., i1 %4, ...)
   ret %jl_value_t.0* %5

  Bools (that are the result of direct truncs) are lowered as whatever
  the argument to the trunc was and a "and 1", causing the part of the
  MBB responsible for this argument to look something like this:

   %vreg8<def,tied1> = AND8ri %vreg7<kill,tied0>, 1, %EFLAGS<imp-def>; GR8:%vreg8,%vreg7

  Later, when the load is lowered, it will insert

   %vreg15<def> = MOV8rm %vreg14, 1, %noreg, 0, %noreg; mem:LD1[undef] GR8:%vreg15 GR64:%vreg14

  but remember to (at the end of isel) replace vreg7 by vreg15. Now for
  the bug. In fast isel lowering, we mistakenly mark vreg8 as the result
  of the load instead of the trunc. This adds a fixup to have
  vreg8 replaced by whatever the result of the load is as well, so
  we end up with

   %vreg15<def,tied1> = AND8ri %vreg15<kill,tied0>, 1, %EFLAGS<imp-def>; GR8:%vreg15

  which is an SSA violation and causes problems later down the road.

Add a new device control utility for new-bus devices called devctl.  This
allows the user to request administrative changes to individual devices
such as attach or detaching drivers or disabling and re-enabling devices.
- Add a new /dev/devctl2 character device which uses ioctls for device
  requests.  The ioctls use a common 'struct devreq' which is somewhat
  similar to 'struct ifreq'.
- The ioctls identify the device to operate on via a string.  This
  string can either by the device's name, or it can be a bus-specific
  address.  (For unattached devices, a bus address is the only way to
  locate a device.)  Bus drivers register an eventhandler to claim
  unrecognized device names that the driver recognizes as a valid address.
  Two buses currently support addresses: ACPI recognizes any device
  in the ACPI namespace via its full path starting with "\" and
  the PCI bus driver recognizes an address specification of
  'pci[<domain>:]<bus>:<slot>:<func>' (identical to the PCI selector
  strings supported by pciconf).
- To make it easier to cut and paste, change the PnP location string
  in the PCI bus driver to output a full PCI selector string rather
  than 'slot=<slot> function=<func>'.
- Add a devctl(3) interface in libdevctl which provides a wrapper around
  the ioctls and is the preferred interface for other userland code.
- Add a devctl(8) program which is a simple wrapper around the requests
  supported by devctl(3).
- Add a device_is_suspended() function to check DF_SUSPENDED.
- Add a resource_unset_value() function that can be used to remove a
  hint from the kernel environment.  This is used to clear a
  hint.<driver>.<unit>.disabled hint when re-enabling a boot-time
