31c926660f Extend SerializedModuleLoader to load modules from a bitstream. 
Add tools/lldb-moduleimport-test, which simulates LLDB importing modules
from the __apple_ast section in Mach-O files and use it to regression-test
the new API.

9cacf75a8f Revert "Debug info: Class are passed by reference, make class args and local" 
This reverts commit r7639.
Greg found out that we should not be doing this after all, since _all_ classes are references by definition.

cf4e28a70a Debug Info: Change the type caching to be based on the Type instead of 
DebugTypeInfo. This is based off the observation that no two types that
share the same canonical type can have different storage and alignment
and has the benefit of being able to locate the debug info for a type
described by a meta type.

661315763a Debug Info: This patch implements the "emit modules when compiling -g" 
proposal.
When compiling with debug info, build a swiftmodule that contains all the
type decls referenced by DWARF and emit it into a special __apple_swiftast
section in the .o file.

5b5ba6d78a Name mangling: Add a "_Tt" prefix to all type names that are output in 
the debug info, to aid the debugger in figuring out the implementation
language of a given type in multi-language environments.
FYI, where applicable, we also emit the
DW_AT_APPLE_runtime_class(DW_AT_lang_Swift) attribute.
The demangler accepts type names with the "_Tt" prefix without the --type
switch.

611a8bd751 Revert "Debug Info: Add support for enum-style oneof types." 
We're redesigning enums, and the current implementation isn't really
handled in the module format (since it uses the presence or absence of
a source location to decide if a oneof element is "enum-like"). We'll
just drop this from the debug info for now.

This reverts r6462 / 9ed7fb3e70ff2cb9f08524699e89643386e8b6e0.

- Type info is limited to name, location, and storage size.
- As a side-effect: verbose LLVM IR allocas in debug builds!

0f7533dc7e Debug Info! Add basic support for line tables, compilation units, files, 
and lexical scopes, which can be enabled through the new -g option.
When -g is enabled, line tables and scopes compile all the way
down to DWARF.

Changes to SIL:
- In addition to a SILLocation, every instruction now also has a pointer
  to a SILDebugScope (its containing lexical scope).
- Added LexicalScope, which is to be used for all Scopes we want to show
  up in the debug info.
