6378efee04 [IRGen] Bound all reqs of open_pack_element. 
Previously, only the element archetypes that corresponded to the
relevant pack generic parameters were bound, and the wtables that were
bound for them were based on looking up what they conform to.  Here, the
requirements of the generic signature are used to find which archetypes
must be bound to metadata and which conformances must be bound to
wtables.

748264c45f Add a unprotectedStackAlloc builtin 
It's like `Builtin.stackAlloc`, but doesn't set the `[stack_protection]` flag on its containing function.

cef6ef9a84 SIL: add a debug_step instruction 
This instruction can be inserted by Onone optimizations as a replacement for deleted instructions to
ensure that it's possible to single step on its location.

0f4429b224 DebugTypeInfo: Prefer the size of the Storage type derived from the TypeInfo. 
Previously type sizes would be inconsistently sourced from either the LLVM type
or the FixedTypeInfo, depending on the call site. This was problematic because
TypeInfo operates with a resolution of whole bytes, which means that types such
as i1 would get a reported as having a size of 8. This patch now asserts that
all occurrences of the same type have the same size as the first, cached
occurence.

To avoid triggering the cached type verification assertion, this patch avoids
caching of storage-sized containers. It also removes the unique identifier from
forward declarations, which could lead to type confusion during LTO.

159c653780 Add the tuple_pack_element_addr SIL instruction. 
This allows dynamically indexing into tuples.  IRGen not yet
implemented.

I think I'm going to need a type_refine_addr instruction in
order to handle substitutions into the operand type that
eliminate the outer layer of tuple-ness.  Gonna handle that
in a follow-up commit.

6bf9ac858b Add instructions to allocate and deallocate packs. 
Having added these, I'm not entirely sure we couldn't just use
alloc_stack and dealloc_stack.  Well, if we find ourselves adding
a lot of redundancy with those instructions (e.g. around DI), we
can always go back and rip these out.

a9f0b2a84f Remove StorageType from DebugTypeInfo::getErrorResult(). 
Error results are always indirect so passing in the llvm storage type (which is
always a pointer) is entirely pointless.
