Chris Lattner d1acffc845 Change constantexpr global variable initializers to convert the constants 
to MCExpr then emit them through MCStreamer with EmitValue.  I think all
global variable initializers are now going through mcstreamer.

Eric Christopher c1451d764f Don't lower splat vector load to relative to the esp if the 
stack may be misaligned.

Update test accordingly.

do this.

Sean Callanan 5051cb8010 Added the skeleton for the implementation of the X86 
target-specific AsmLexer, and added the appropriate
registration calls.

Sean Callanan 86c1181c3d 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.

Chris Lattner edf96a4cc3 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
...

                                                            ##   Parent Loop BB1_1 Depth=1
                                                            ## =>  This Loop Header: Depth=2

Chris Lattner e567c8e67f 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.

Chris Lattner 23e43dbba1 reenable the label loop comments and switch them to use the formatted

Torok Edwin fbcd2c76d5 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.
