Refactor the SROA visitors for partitioning an alloca and building
partition use lists a bit. No functionality changed.

These visitors are actually visiting a tuple of a Use and an offset into
the alloca. However, we use the InstVisitor to handle the dispatch over
the users, and so the Use and Offset are stored in class member
variables and set just before each call to visit(). This is fairly
awkward and makes the functions a bit harder to read, but its the only
real option we have until InstVisitor can be rewritten to use variadic
templates.

However, this pattern shouldn't be followed on the helper member
functions where there is no interface constraint from the visitor. We
already were passing the instruction as a normal parameter rather than
use the Use to get at it, start passing the offset as well. This will
become more important in subsequent patches as the offset will in some
cases change while visiting a single instruction.

Implemented HiPE Calling Convention

Implemented a new calling convention (cc 11) for HiPE similar to GHC's cc 10.
In detail:
 * Inserted new symbol "cc 11" (CallingConv::HiPE).
 * Created cc and retcc for both 32 and 64 bit.
 * HiPE cc defines no calleE-save registers (use CSR_NoRegs).
 * HiPE cc supports tail call optimization.
 * HiPE cc uses GR32RegClass for tail calls.
HiPE prologue code emission for X86 (modify PEI)
A Garbage Colleciton plugin for HiPE's gc scheme

Implementation of a custom gc plugin to write specific stack descriptor
information in ".note.gc" of an Elf64 object file. This information is parsed
with an Erlang binary parser and transformed to special data structures to be
loaded by Erlang/OTP system's loader.
