Refactor attribute stripping for libbcc and llvm-rs-as.
There is an existing StripUnknownAttributes pass we use to remove
attributes unknown to old versions of LLVM before writing out bitcode.
This is needed to avoid errors when writing or reading the bitcode.
This change does three things:
- Refactors code so that we can strip unknown attributes without
depending on the pass infrastructure, and so that we have a library
to strip unknown attributes. This is needed so that we can use this
functionality in places where we're not using the pass manager and
so that we can use it outside of slang (specifically, in libbcc).
- Strips unknown attributes in llvm-rs-as, in order to satisfy
frameworks/compile/libbcc/tests/run-lit-tests.sh
(test_reduce_general_metadata.ll). See details below.
- Updates some stale comments.
Why do we need to strip unknown attributes in llvm-rs-as, even if the
input .ll does not contain those attributes? Because the LLVM parser
calls llvm::UpgradeCallsToIntrinsic() to canonicalize the attributes
of intrinsic functions. For example, test_reduce_general_metadata.ll
contains a call to @llvm.memcpy.p0i8.p0i8.i64, which gets
canonicalized to have the argmemonly attribute.
Remember that we're writing an old fixed version of bitcode, older
than the "native" LLVM IR we're using, so there may be attributes in
that IR that are not representible in that old fixed version of
bitcode. Furthermore, argmemonly is one of a set of attributes that
seem to be designed as "transient" -- they can appear in the IR
(possibly only on intrinsics, or as the result of some analysis?) but
can never appear in bitcode.

Fix slang to compile with LLVM r275480
Bug: http://b/31320715
In addition to fixing compilation with the new LLVM sources, this change
also switches to using LLVM's RenderScript triples. Clang also uses
this triple to set the size and alignment of 'long' data type to
64-bits. We no longer need/have the '+long64' CPU feature.
Test: Run RenderScript tests (host tests for slang and libbcc, RsTest, CTS)

Added in fix to allow generation of valid debug info
Changed the bitcode writer of the llvm-rs-cc compiler
to use the current version of llvm when generating debug
metadata. If the debug info is generated with the current
fixed version writers the resulting bitcode is invalid and
will fail verification in the bcc compiler. However, this
means that, currently, only revisions which have compatible
versions of llvm will work. The incompatibility is in the
debug info generation in slang and the verification/backend
in bcc. If bcc is expecting the debug info to be in a different
format that slang outputs the verification stage will fail. As
things stand only the newest revision will work, as the debug
info in AOSP LLVM was updated a few weeks ago. If the debug
bitcode is ahead of the reader on the device it will fail the
bitcode verification stage in bcc.

llvm-rs-as: Wrap bitcode with the RS bitcode wrapper.
Change llvm-rs-as and llvm-rs-cc to use the same code path when it comes
to writing bitcode. As a result llvm-rs-as can take a *.ll file and
output a *.bc file containing the RenderScript bitcode wrapper, so that
code produced by llvm-rs-as can be read by bcinfo.

The -bitcode-version flags allows to specify the version of the
bitcode that should be emitted.
