d04a8d4b33 Use the new script to sort the includes of every file under lib. 
Sooooo many of these had incorrect or strange main module includes.
I have manually inspected all of these, and fixed the main module
include to be the nearest plausible thing I could find. If you own or
care about any of these source files, I encourage you to take some time
and check that these edits were sensible. I can't have broken anything
(I strictly added headers, and reordered them, never removed), but they
may not be the headers you'd really like to identify as containing the
API being implemented.

Many forward declarations and missing includes were added to a header
files to allow them to parse cleanly when included first. The main
module rule does in fact have its merits. =]

158413930f Bundle jump/branch instructions with the instructions in the delay slot in 
delay slot filler pass of MIPS, per suggestion of Jakob Stoklund Olesen.

This change, along with the fix in r158154, enables machine verification
to be run after delay slot filling.

f9c3f3b8a8 Add a command line option to skip the delay slot filler pass entirely for Mips. 
The purpose of this option is to silence error messages issued by machine
verifier passes and enable them to run to the end. If this option is not
provided, -verify-machineinstrs complains when it discovers there is a
non-terminator instruction (an instruction that is in a delay slot) after the
first terminator in a basic block.

5a96b3dad2 Add bundle aware API for querying instruction properties and switch the code 
generator to it. For non-bundle instructions, these behave exactly the same
as the MC layer API.

For properties like mayLoad / mayStore, look into the bundle and if any of the
bundled instructions has the property it would return true.
For properties like isPredicable, only return true if *all* of the bundled
instructions have the property.
For properties like canFoldAsLoad, isCompare, conservatively return false for
bundles.
