abde584fd1 Stop passing the gold plugin path to llvm-ar.
llvm-ar takes a --plugin argument but it is ignored for compatibility,
so passing it has no effect.

Peter Collingbourne
486e42c353 Enable safe ICF with LLD.
Support for safe ICF was added to LLD in LLVM r337429. This reduces
the size of sailfish system.img by 7.6MB.

The address-significance tables created by Clang to support LLD's
implementation of safe ICF are incompatible with ld -r. Therefore we
need to pass -fno-addrsig to the compiler to prevent it from creating
an address-significance table when building a cc_object.

98d8580c3a Prevent clang from using the x18 register on arm64.
This is achieved via the compiler flag -ffixed-x18 for non-LTO builds
and the linker flag -plugin-opt -mattr=+reserve-x18 for LTO builds.

This change should be reverted once we upgrade past LLVM r340889
which does this by default on Android.

1ffac8e636 Enable SHT_RELR sections to encode relative relocations.
Proposal for adding SHT_RELR sections in the generic-abi is at
https://groups.google.com/forum/#!topic/generic-abi/bX460iggiKg

This CL requires clang-r328903.

The following test results are on clang-r339409.

Size comparison for "aosp_marlin-userdebug":
$ du -B1 -s {none,pack,relr,both}/out/target/product/marlin/system
1014616064      none/out/target/product/marlin/system
1001074688      pack/out/target/product/marlin/system
1004273664      relr/out/target/product/marlin/system
1000099840      both/out/target/product/marlin/system

none contains a build with no packing (--pack-dyn-relocs=none).
pack contains a build with current settings (--pack-dyn-relocs=android).
relr contains a build with relr packing only (--pack-dyn-relocs=relr).
both contains a build with both options enabled (--pack-dyn-relocs=android+relr).

With --pack-dyn-relocs=android+relr, lld will encode the relative
relocations in a SHT_ANDROID_RELR section, and pack the rest of
the dynamic relocations in a SHT_ANDROID_REL(A) section.

--pack-dyn-relocs=android was saving us 13,541,376 bytes (1.35%) (none - pack).
--pack-dyn-relocs=relr will save us 10,342,400 bytes (1.03%) (none - relr).
--pack-dyn-relocs=android+relr is saving us 14,516,224 bytes (1.45%) (none - both).

Size comparison for the "system/bin" directory:
$ du -B1 -s {none,pack,relr,both}/out/target/product/marlin/system/bin

28258304        relr/out/target/product/marlin/system/bin
28180480        both/out/target/product/marlin/system/bin

--pack-dyn-relocs=android was saving us 1,093,632 bytes (3.72%) (none - pack).
--pack-dyn-relocs=relr will save us 1,155,072 bytes (3.93%) (none - relr).
--pack-dyn-relocs=android+relr is saving us 1,232,896 bytes (4.19%) (none - both).

61f2d11e75 Remove flags from ClangLibToolingUnknownCflags
This commit removes flags from ClangLibToolingUnknownCflags.  These
flags were added to workaround an old version of clang in
`external/clang`.  Since we have updated to clang-r339409b, we don't
need these workaround anymore.

ad73b2e18a Scudo minimal runtime support for Soong
Scudo is now compatible with the -fsanitize-minimal-runtime, and offers a new
dynamic library that doesn't bundle UBSan.

This patch adds support for this new library in Soong, preferring it over the
full one, unless a UBSan or diagnostic dependency is found.

Test: aosp compiled with m -j
Test: local test enabling Scudo for tombstoned

a403cc7254 Change STL for Windows to libc++.
- Stop including libstdc++ headers.
- '-pthread' and 'static-libgcc' are unused when we pass -nodefaultlibs.
We didn't pass -nodefaultlibs for libstdc++.
- Use SjLj exceptions for 32-bit.  libgcc_eh implements SjLj exception
model for 32-bit.
- Disable visibility annotations for libcxx and libcxxabi since we are
only going to support these as static libraries.
- Use Win32 threads.  MinGW pthreads throws an error when building
libcxx since it's pthread_mutex_initializer is not constant (needs a
cast).
- Link libgcc_eh, which needs pthread, which in turn depends on
kernel32.  Wrap the libraries with --start-group and --end-group and
remove duplicates.

Test: Build and test Windows binaries under Wine.

version (which did not have these lld bits) was already merged there.
