Turn stdout into binary mode during bitcode emission.
This is necessary on windows targets, since stdout is in text mode there.

There's definately more to come here, but I'm checking this
basic support in now to make it available to people who are
interested.

Allow an extra bit for CommonLinkage.

This changes the .bc file format, but if I understand
how it works correctly, old .bc files continue to
be readable.

Add CommonLinkage; currently tentative definitions
are represented as "weak", but there are subtle differences
in some cases on Darwin, so we need both. The intent
is that "common" will behave identically to "weak" unless
somebody changes their target to do something else.
No functional change as yet.

Reimplement the parameter attributes support, phase #1. hilights:

1. There is now a "PAListPtr" class, which is a smart pointer around
the underlying uniqued parameter attribute list object, and manages
its refcount. It is now impossible to mess up the refcount.
2. PAListPtr is now the main interface to the underlying object, and
the underlying object is now completely opaque.
3. Implementation details like SmallVector and FoldingSet are now no
longer part of the interface.
4. You can create a PAListPtr with an arbitrary sequence of
ParamAttrsWithIndex's, no need to make a SmallVector of a specific
size (you can just use an array or scalar or vector if you wish).
5. All the client code that had to check for a null pointer before
dereferencing the pointer is simplified to just access the
PAListPtr directly.
6. The interfaces for adding attrs to a list and removing them is a
bit simpler.

Phase #2 will rename some stuff (e.g. PAListPtr) and do other less
invasive changes.

Honour aliases visibility when reading from/writing to bitcode

Add an unwind_to field to basic blocks, making them Users instead of Values.
This is the first checkin for PR1269, the new EH infrastructure.

llvm-svn: 47802

Remove debugging help.

llvm-svn: 47585

Update bitcode reader and writer to handle multiple return values.
Take 2.

Backing out r47521 for now. This has broken a number of tests.

llvm-svn: 47533

Properly read and write bitcodes for multiple return values.

llvm-svn: 47521

Split ParameterAttributes.h, putting the complicated
stuff into ParamAttrsList.h. Per feedback from
ParamAttrs changes.

llvm-svn: 47504

Read and write getresult.

llvm-svn: 47471

Support alignment within ParamAttrs in the I/O handling.

llvm-svn: 47401

Expand ParameterAttributes to 32 bits (in preparation
for adding alignment info, not there yet). Clean up
interfaces to reference ParameterAttributes consistently.

Remove attribution from file headers, per discussion on llvmdev.

Implement address space attribute for LLVM pointer types. Address spaces are
regions of memory that have a target specific relationship, as described in the
Embedded C Technical Report.

This also implements the 2007-12-11-AddressSpaces test,
which demonstrates how address space attributes can be used in LLVM IR.

In addition, this patch changes the bitcode signature for stores (in a backwards
compatible manner), such that the pointer type, rather than the pointee type, is
encoded. This permits type information in the pointer (e.g. address space) to be
preserved for stores.

LangRef updates are forthcoming.

Adding a collector name attribute to Function in the IR. These
methods are new to Function:

bool hasCollector() const;
const std::string &getCollector() const;
void setCollector(const std::string &);
void clearCollector();

The assembly representation is as such:

define void @f() gc "shadow-stack" { ...

The implementation uses an on-the-side table to map Functions to
collector names, such that there is no overhead. A StringPool is
further used to unique collector names, which are extremely
likely to be unique per process.
