531ed64b09 Run the functionattrs pass after the inliner, and not before. 
This makes both logical sense (see below) and increases the
number of functions marked readnone/readonly by about 1-2%
in practice.  The number of functions marked nocapture goes
up by about 5-10%.  The reason it makes sense is shown by
the following example: if you run -functionattrs -inline on
it, then no attributes are assigned.  But if you instead run
-inline -functionattrs then @f is marked readnone because the
simplifications produced by the inliner eliminate the store.

@x = external global i32

define void @w(i1 %b) {
        br i1 %b, label %write, label %return
write:
        store i32 1, i32 *@x
        br label %return
return:
        ret void
}

define void @f() {
        call void @w(i1 0)
        ret void
}

97331f70ca For Thumb indirect branches, use "mov pc, reg" which does not switch 
between ARM/Thumb modes and does not require the low bit of the target
address to be set for Thumb.

b3bc38f392 CMake: Report an error if there is an unknown .cpp file in a source 
directory.

This is useful in case someone who works with the config&make build
system forgot to add a file to its CMakeLists.txt. Instead of
obtaining undefined references at link time, cmake will complain at
configure time on the first build after a svn update.

ec5cb0cdbd Initilize the machine LICM CSE map upon the first time an instruction is hoisted to 
the loop preheader. Add instructions which are already in the preheader block that
may be common expressions of those that are hoisted out. These does get a few more
instructions CSE'ed.
