Previously these 2 instructions:
%p = bitcast [100 x {i8,i8,i8}]* %x to i8*
%q = getelementptr i8* %p, i32 -4
were combined into:
%q = getelementptr [100 x { i8, i8, i8 }]* %x, i32 0,
i32 1431655764, i32 0
what was incorrect.

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 Ocaml bindings for the bitreader as requested by Sarah

Thompson. Usage should be something like this:
open Llvm
open Llvm_bitreader
match read_bitcode_file fn with
| Bitreader_failure msg ->
prerr_endline msg
| Bitreader_success m ->
...;
dispose_module m
Compile with: ocamlc llvm.cma llvm_bitreader.cma

These should probably be something like:
CFI(".cfi_def_cfa_offset 16\n")
where CFI is defined to a noop on darwin and other platforms
that don't support those directives.

Fix PR1836: in the interpreter, read and write apints
...
using the minimum possible number of bytes. For little
endian targets run on little endian machines, apints are
stored in memory from LSB to MSB as before. For big endian
targets on big endian machines they are stored from MSB to
LSB which wasn't always the case before (if the target and
host endianness doesn't match values are stored according
to the host's endianness). Doing this requires knowing the
endianness of the host, which is determined when configuring -
thanks go to Anton for this. Only having access to little
endian machines I was unable to properly test the big endian
part, which is also the most complicated...

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.
