d50d17e067 Added the skeleton for the implementation of the X86 
target-specific AsmLexer, and added the appropriate
registration calls.

1942b96584 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.

576e41a375 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   0                                           ## @TType Encoding = absptr
        .byte   0x28                                        ## @TType base offset
        .byte   3                                           ## Call site Encoding = udata4
        .byte   0x1a                                        ## Call site table size

7b52485bbd Filled out the skeleton of the TargetAsmLexer to behave 
exactly like an MCAsmLexer.  (The difference is that the
TargetAsmLexer knows how to handle target-specific stuff
like registers, whereas the MCAsmLexer is fully generic.)

92531ea22d make the loop comment printer print out a much better structured

                                                            ##   Parent Loop BB1_1 Depth=1
                                                            ## =>  This Loop Header: Depth=2
                                                            ##       Child Loop BB1_8 Depth 3
                                                            ##       Child Loop BB1_6 Depth 3

bc2e117803 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.

46925cc515 Fix TimeValue::now() on Unix. 
TimeValue()::now().toEpochTime() is supposed to be the same as time(),
but it wasn't, because toEpoch subtracted PosixZeroTime, but now()
didn't add PosixZeroTime!
Add a unittest to check this works.
