6ffce6fa92 Remove "localize global" optimization
Summary:
As discussed in http://llvm-reviews.chandlerc.com/D1754,
this optimization isn't really valid for C, and fires too rarely anyway.

I really should sort it or do something more sustainable, but I couldn't

This was broken when options were moved up in r191680. No test because this is
specific LLVMgold.so/libLTO.so.

1a1d7c4f4c Don't layout items in a list in columns. That requires changing every
line just to add or remove a single element. What I wouldn't give to
have clang-format here an be able to format this more densely without

Re-group and sort the entries while here to make the whole thing more
clear.

6eb43d2956 This threads SectionName through the allocateCodeSection/allocateDataSection APIs, both in C++ and C land.
It's useful for the memory managers that are allocating a section to know what the name of the section is.  
At a minimum, this is useful for low-level debugging - it's customary for JITs to be able to tell you what 
memory they allocated, and as part of any such dump, they should be able to tell you some meta-data about 
what each allocation is for.  This allows clients that supply their own memory managers to do this.  
Additionally, we also envision the SectionName being useful for passing meta-data from within LLVM to an LLVM 
client.

This changes both the C and C++ APIs, and all of the clients of those APIs within LLVM.  I'm assuming that 
it's safe to change the C++ API because that API is allowed to change.  I'm assuming that it's safe to change 
the C API because we haven't shipped the API in a release yet (LLVM 3.3 doesn't include the MCJIT memory 
management C API).

2b53089bd0 Debug Info: In DIBuilder, the derived-from field of a DW_TAG_pointer_type
is updated to use DITypeRef.

Move isUnsignedDIType and getOriginalTypeSize from DebugInfo.h to be static
helper functions in DwarfCompileUnit. We already have a static helper function
"isTypeSigned" in DwarfCompileUnit, and a pointer to DwarfDebug is added to
resolve the derived-from field. All three functions need to go across link
for derived-from fields, so we need to get hold of a type identifier map.

A pointer to DwarfDebug is also added to DbgVariable in order to resolve the
derived-from field.

Debug info verifier is updated to check a derived-from field is a TypeRef.
Verifier will not go across link for derived-from fields, in debug info finder,
we go across the link to add derived-from fields to types.

Function getDICompositeType is only used by dragonegg and since dragonegg does
not generate identifier for types, we use an empty map to resolve the
derived-from field.

When printing a derived-from field, we use DITypeRef::getName to either return
the type identifier or getName of the DIType.

A paired commit at clang is required due to changes to DIBuilder.

620f436b20 Debug Info: remove duplication of DIEs when a DIE is part of the type system
and it is shared across CUs.

We add a few maps in DwarfDebug to map MDNodes for the type system to the
corresponding DIEs: MDTypeNodeToDieMap, MDSPNodeToDieMap, and
MDStaticMemberNodeToDieMap. These DIEs can be shared across CUs, that is why we
keep the maps in DwarfDebug instead of CompileUnit.

Sometimes, when we try to add an attribute to a DIE, the DIE is not yet added
to its owner yet, so we don't know whether we should use ref_addr or ref4.
We create a worklist that will be processed during finalization to add
attributes with the correct form (ref_addr or ref4).

We add addDIEEntry to DwarfDebug to be a wrapper around DIE->addValue. It checks
whether we know the correct form, if not, we update the worklist
(DIEEntryWorklist).

A testing case is added to show that we only create a single DIE for a type
MDNode and we use ref_addr to refer to the type DIE.

c269c4f505 Add non-blocking Wait() for launched processes
- New ProcessInfo class to encapsulate information about child processes.
- Generalized the Wait() to support non-blocking wait on child processes.
- ExecuteNoWait() now returns a ProcessInfo object with information about
  the launched child. Users will be able to use this object to
  perform non-blocking wait.
- ExecuteNoWait() now accepts an ExecutionFailed param that tells if execution
  failed or not.

These changes will allow users to implement basic process parallel
tools.
