pretty printing encoding comments and eliminates redundancy on
the client side.  We now get pretty dwarf like this again:

        .byte   255                                         ## @LPStart Encoding = omit
        .byte   0                                           ## @TType Encoding = absptr
        .byte   0x28                                        ## @TType base offset
        .byte   3                                           ## Call site Encoding = udata4
        .byte   0x1a                                        ## Call site table size
...

and much more accurately describes what it is all about.

output.  An example:

        .align  4, 0x90
LBB1_5:                                                     ## %while.cond3
                                                            ##   Parent Loop BB1_1 Depth=1
                                                            ## =>  This Loop Header: Depth=2
                                                            ##       Child Loop BB1_8 Depth 3
                                                            ##       Child Loop BB1_6 Depth 3

llvm-svn: 94225

For loop headers, print Inner loop along with the other stuff so it doesn't take
an extra line.  We now get stuff like this:

LBB1_4:                                                     ## %land.end
                                                            ##   in Loop: Header=BB1_1 Depth=1
        notb    %al
        testb   $1, %al
        jne     LBB1_8

and:

LBB1_6:                                                     ## %while.cond7
                                                            ## Inner Loop Header: Depth=3
                                                            ##     Inside Loop BB1_5 Depth 2
                                                            ##   Inside Loop BB1_1 Depth 1

which still isn't great for loop headers, but is much less verbose.

comment emission stuff.  I'm going to rewrite this though because the
current output doesn't make sense.

llvm-svn: 94215

AddComment and GetCommentOS.  Add a blank line between globals
(even in non-verbose mode) to make the assembly more readable.

LoopStrengthReduce, as it's causing too much trouble (even with the
old LoopStrengthReduce code).

llvm-svn: 94172

Switch over the asm-verbose comment for double values to use it.  We now get:

_x:
	.long	343597384                                   ## double 1.231200e+02
	.long	1079953326

For example, note that the comment is on the same line as the .long.  Woo.

missing ones are libsupport, libsystem and libvmcore.  libvmcore is
currently blocked on bugpoint, which uses EH.  Once it stops using
EH, we can switch it off.

This #if 0's out 3 unit tests, because gtest requires RTTI information.
Suggestions welcome on how to fix this.

Teach pre-regalloc scheduler to schedule loads from nearby addresses. It may improve cache locality. This is controlled by -cluster-loads for now.
