Jeffrey Yasskin b40d3f76a0 Fix DenseMap iterator constness.
This patch forbids implicit conversion of DenseMap::const_iterator to
DenseMap::iterator which was possible because DenseMapIterator inherited
(publicly) from DenseMapConstIterator. Conversion the other way around is now
allowed as one may expect.

The template DenseMapConstIterator is removed and the template parameter
IsConst which specifies whether the iterator is constant is added to
DenseMapIterator.

Actually IsConst parameter is not necessary since the constness can be
determined from KeyT but this is not relevant to the fix and can be addressed
later.

Patch by Victor Zverovich!

Jakob Stoklund Olesen c7cfc94bcc Print out an informative comment for KILL instructions.
The KILL pseudo-instruction may survive to the asm printer pass, just like the IMPLICIT_DEF. Print the KILL as a comment instead of just leaving a blank line in the output.

With -asm-verbose=0, a blank line is printed, like IMPLICIT?DEF.

Dan Gohman 10d3dc569b Instead of printing unnecessary basic block labels as labels in
verbose-asm mode, print comments instead. This eliminates a non-comment
difference between verbose-asm mode and non-verbose-asm mode.

Also, factor out the relevant code out of all the targets and into
target-independent code.

Chris Lattner fdd8790718 strength reduce a ton of type equality tests to check the typeid (Through

Bob Wilson b633d7a665 Add a new virtual EmitStartOfAsmFile method to the AsmPrinter and use this
to emit target-specific things at the beginning of the asm output.  This
fixes a problem for PPC, where the text sections are not being kept together
as expected.  The base class doInitialization code calls DW->BeginModule()
which emits a bunch of DWARF section directives.  The PPC doInitialization
code then emits all the TEXT section directives, with the intention that they
will be kept together. But as I understand it, the Darwin assembler treats
the default TEXT section as a special case and moves it to the beginning of
the file, which means that all those DWARF sections are in the middle of
the text.  With this change, the EmitStartOfAsmFile hook is called before
the DWARF section directives are emitted, so that all the PPC text section
directives come out right at the beginning of the file.
