Unnamed bitfields cause struct layout problems

We currently can't do this for ObjC since the DW_AT_bit_offset value for any direct ivars of ObjC classes as the values for these attributes are bogus. A bug has been filed on Clang to fix this, and another bug has been filed on LLDB to make sure we fix the DWARF parser once the clang fix is in by looking the the DW_AT_producer in the compile unit attributes and finding the compiler version and only enabling it for newer versions of clang.

Add a method to indicate section address re-assignment is finished.
Prior to this patch RuntimeDyld attempted to re-apply relocations every time reassignSectionAddress was called (via MCJIT::mapSectionAddress). In addition to being inefficient and redundant, this led to a problem when a section was temporarily moved too far away from another section with a relative relocation referencing the section being moved. To fix this, I'm adding a new method (finalizeObject) which the client can call to indicate that it is finished rearranging section addresses so the relocations can safely be applied.

While we're here, extend the module map to cover most of the
newly-added instrinsic headers. Only wmmintrin.h is missing, because
it needs to be split into AES/PCLMUL subheaders (as a separate commit).

Hash the various compiler version, target, preprocessor, and
header-search options into the module hash. We're just using
ADT/Hashing.hpp for this, which isn't as cryptographically strong as
I'd like, but it'll do. If someone contributes (say) and MD4
implementation, we'd happily switch to that.

On PowerPC64, integer return values (as well as arguments) are supposed
to be extended to a full register. This is modeled in the IR by marking
the return value (or argument) with a signext or zeroext attribute.
However, while these attributes are respected for function arguments,
they are currently ignored for function return values by the PowerPC
back-end. This patch updates PPCCallingConv.td to ask for the promotion
to i64, and fixes LowerReturn and LowerCallResult to implement it.
The new test case verifies that both arguments and return values are
properly extended when passing them; and also that the optimizers
understand incoming argument and return values are in fact guaranteed
by the ABI to be extended.
The patch caused a spurious breakage in CodeGen/PowerPC/coalesce-ext.ll,
since the test case used a "ret" instruction to create a use of an i32
value at the end of the function (to set up data flow as required for
what the test is intended to test). Since there's now an implicit
promotion to i64, that data flow no longer works as expected. To fix
this, this patch now adds an extra "add" to ensure we have an appropriate
use of the i32 value.

On PowerPC64, integer arguments and return values need to be sign- or
zero-extended to 64 bits. This information is currently provided to
the back end by setting "signext" or "zeroext" attributes. However,
this is done only for integer types *smaller* than i32, not for i32
itself. This causes clang to generate code violating the ABI, which
results in a failure of the tramp3d-v4 test case (due to calling a
system library routine without ABI-required extension).
This patch implements custom versions of classifyArgumentType and
classifyReturnType for PPC64_SVR4_ABIInfo, which are the same as the
default versions except that they also classify "int" and "unsigned int"
as types needing extending. This fixed tramp3d-v4 on PowerPC64.
