DWARF Type Hashing: Include reference and rvalue reference type in the declarable summary hashing path

More support for 7.25 Part 5.

There are several other tag types that need similar handling but to
ensure test coverage they'll be coming incrementally.

This uses a map, keeping the type DIE numbering separate from the DIEs
themselves - alternatively we could do things the way GCC does if we
want to add an integer to the DIE type to record the numbering there.

This allows various variables to be more self-documenting and easier to
debug by being of specific types without overlapping enum values.

Precommit review by Eric Christopher.

Found while adding type safety to the various DWARF enumerations (form,
attribute, tag, etc) that caused Clang to warn on an incompletely
covered switch. Converting the comment to a default/unreachable
uncovered this case of an unsupported form encoding. Seems we were
skipping fission strings entirely.

This ensures that the prefix data is treated as part of the function for
the purpose of debug info.  This provides a better debugging experience,
among other things by allowing a debug info client to correctly look up
a function in debug info given a function pointer.

With this commit, all DIEs created in CompileUnit will be added to parents
inside the same function. Also make getOrCreateTemplateType|Value functions
private.

No functionality change.

Makes the uses more terse and requires that they use a semicolon at the
end that helps editors indent proceeding lines correctly.

like C++ should be the fully qualified names for the type.

Add a routine that does a language specific context walk to build
up the qualified name and use it when we add types/names to the
tables. Expand the gnu pubnames testcase as it's the most complex
to make sure that qualified types are also being added.

examples.

1) Make sure we emit static member variables by checking
at the end of createGlobalVariableDIE rather than piecemeal
in the function.
(As a note, createGlobalVariableDIE needs rewriting.)

2) Make sure we use the definition rather than declaration DIE
for two things: a) determining linkage for gnu pubnames, and b)
as the address of the DIE for global variables.
(As a note, createGlobalVariableDIE really needs rewriting.)

Adjust the testcase to make sure we're checking the correct DIEs.

twice and just look up the value. Fix the one case where
we were trying to create a subprogram DIE and we should already
have had one. Reflow formatting in collectDeadVariables while fixing.

llvm-svn: 192749

llvm-svn: 192731

Clean up creation of static member DIEs. We can create static member DIEs from
two places, so we call getOrCreateStaticMemberDIE from the two places.

getOrCreateStaticMemberDIE will get or create the context DIE first, then it
will check if the DIE already exists, if not, we create the static member DIE
and add it to the context.

Creation of static member DIEs are handled in a similar way as subprogram DIEs.

llvm-svn: 192618

The form must be a reference form in addDIEEntry. Which reference form to
use will be decided by the callee.

No functionality change.

llvm-svn: 192517

Make AsmPrinter::emitImplicitDef a virtual method so targets can emit custom comments for implicit defs

For NVPTX, this fixes a crash where the emitImplicitDef implementation was expecting physical registers,
while NVPTX uses virtual registers (with a couple of exceptions).  Now, the implicit def comment will be
emitted as a true PTX register name. Other targets can use this to customize the output of implicit def
comments.

This patch fixes an old FIXME by creating a MCTargetStreamer interface
and moving the target specific functions for ARM, Mips and PPC to it.

The ARM streamer is still declared in a common place because it is
used from lib/CodeGen/ARMException.cpp, but the Mips and PPC are
completely hidden in the corresponding Target directories.

I will send an email to llvmdev with instructions on how to use this.
