interfaces to reference ParameterAttributes consistently.

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.

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.

the function type, instead they belong to functions
and function calls. This is an updated and slightly
corrected version of Reid Spencer's original patch.
The only known problem is that auto-upgrading of
bitcode files doesn't seem to work properly (see
test/Bitcode/AutoUpgradeIntrinsics.ll). Hopefully
a bitcode guru (who might that be? :) ) will fix it.

No compile-time support for constant operations yet,
just format transformations. Make readers and
writers work. Split constants into 2 doubles in
Legalize.

Use APFloat in UpgradeParser and AsmParser.
Change all references to ConstantFP to use the
APFloat interface rather than double. Remove
the ConstantFP double interfaces.
Use APFloat functions for constant folding arithmetic
and comparisons.
(There are still way too many places APFloat is
just a wrapper around host float/double, but we're
getting there.)

1. Always use % for local and @ for global.
2. Replace NameNeedsQuotes with QuoteNameIfNeeded so that any adjustments
to the name can be done in one pass.
3. Implement generation of hex escapes so we don't get "wonky" characters
in the output.

Due to darwin gcc bug, one version of darwin linker coalesces
static const int, which defauts PassID based pass identification.

Make ParamAttrsList objects unique. You can no longer directly create or
destroy them but instead must go through the ParamAttrsList::get()
interface.

Put the parameter attributes in their own ParamAttr name space. Adjust the
rest of llvm as a result.

Radically simplify the SlotMachine. There is no need to keep Value planes
around any more. This change causes slot numbering to number all un-named,
non-void values starting at 0 and incrementing monotonically through the
function, regardless of type (including BasicBlocks). Getting slot numbers
is now a single lookup operation instead of a double lookup.

This patch replaces the SymbolTable class with ValueSymbolTable which does
not support types planes. This means that all symbol names in LLVM must now
be unique. The patch addresses the necessary changes to deal with this and
removes code no longer needed as a result. This completes the bulk of the
changes for this PR. Some cleanup patches will follow.
