e9b466d4f0 Modified the register matcher function in AsmMatcher to 
be static.  Also made it possible for clients to get it
and no other functions from ...GenAsmMatcher.inc by
defining REGISTERS_ONLY before including GenAsmMatcher.inc.
This sets the stage for target-specific lexers that can
identify registers and return AsmToken::Register as
appropriate.

f61ed8eb32 add a new DwarfPrinter::EmitEncodingByte method which handles 
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   0x28                                        ## @TType base offset
        .byte   3                                           ## Call site Encoding = udata4
        .byte   0x1a                                        ## Call site table size

5635156203 Filled out the skeleton of the TargetAsmLexer to behave

TargetAsmLexer knows how to handle target-specific stuff
like registers, whereas the MCAsmLexer is fully generic.)

965df54254 For blocks that are not loop headers, just print their loop depth and header BB. 
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.
