[scudo] Refactor of CRC32 and ARM runtime CRC32 detection
Summary:
ARM & AArch64 runtime detection for hardware support of CRC32 has been added
via check of the AT_HWVAL auxiliary vector.
Following Michal's suggestions in D28417, the CRC32 code has been further
changed and looks better now. When compiled with full relro (which is strongly
suggested to benefit from additional hardening), the weak symbol for
computeHardwareCRC32 is read-only and the assembly generated is fairly clean
and straight forward. As suggested, an additional optimization is to skip
the runtime check if SSE 4.2 has been enabled globally, as opposed to only
for scudo_crc32.cpp.
scudo_crc32.h has no purpose anymore and was removed.

[CMake] Support platform building builtins without a full toolchain
Summary:
This patch adds support for building lib/builtins without a fully functioning toolchain. It allows you to bootstrap a cross-compiler, which previously couldn't be done with CMake.
This patch contains the following specific changes:
* Split builtin-specific code out of config-ix.cmake into builtin-config-ix.cmake
* Split some common CMake functionality needed by both builtins and sanitizers into base-config-ix.cmake
* Made lib/builtins/CMakeLists.txt able to be a top-level CMake configuration
I have tested this on Darwin targeting embedded Darwin, and on FreeBSD x86_64 targeting FreeBSD AArch64.
This patch depends on http://reviews.llvm.org/D19692, and is the last part of http://reviews.llvm.org/D16653.

[CMake] Add experimental support for building compiler-rt for iOS
Summary:
This is a reunification of three separate reviews D11073, D11082, D11083.
Having them separate was not constructive even though the patches were smaller because it led to fragmented conversations, and this is really all about one change.
This patch incorporates feedback from samsonov, and refactors the hacky darwin code out of the root CMakeLists.txt and int config-ix.cmake.

[CMake] Add experimental support for building compiler-rt for iOS
Summary:
This is a reunification of three separate reviews D11073, D11082, D11083.
Having them separate was not constructive even though the patches were smaller because it led to fragmented conversations, and this is really all about one change.
This patch incorporates feedback from samsonov, and refactors the hacky darwin code out of the root CMakeLists.txt and int config-ix.cmake.

[HWASan] Port HWASan to Linux x86-64 (compiler-rt)
Summary:
Porting HWASan to Linux x86-64, first of the three patches, compiler-rt part.
The approach is similar to ARM case, trap signal is used to communicate
memory tag check failure. int3 instruction is used to generate a signal,
access parameters are stored in nop [eax + offset] instruction immediately
following the int3 one
Had to add HWASan init on malloc because, due to much less interceptors
defined (most other sanitizers intercept much more and get initalized
via one of those interceptors or don't care about malloc), HWASan was not
initialized yet when libstdc++ was trying to allocate memory for its own
fixed-size heap, which led to CHECK-fail in AllocateFromLocalPool.
Also added the CHECK() failure handler with more detailed message and
stack reporting.

[CMake] Add experimental support for building compiler-rt for iOS
Summary:
This is a reunification of three separate reviews D11073, D11082, D11083.
Having them separate was not constructive even though the patches were smaller because it led to fragmented conversations, and this is really all about one change.
This patch incorporates feedback from samsonov, and refactors the hacky darwin code out of the root CMakeLists.txt and int config-ix.cmake.

[sanitizer] Initial implementation of a Hardened Allocator
Summary:
This is an initial implementation of a Hardened Allocator based on Sanitizer Common's CombinedAllocator.
It aims at mitigating heap based vulnerabilities by adding several features to the base allocator, while staying relatively fast.
The following were implemented:
- additional consistency checks on the allocation function parameters and on the heap chunks;
- use of checksum protected chunk header, to detect corruption;
- randomness to the allocator base;
- delayed freelist (quarantine), to mitigate use after free and overall determinism.
Additional mitigations are in the works.

[scudo] 32-bit and hardware agnostic support
Summary:
This update introduces i386 support for the Scudo Hardened Allocator, and
offers software alternatives for functions that used to require hardware
specific instruction sets. This should make porting to new architectures
easier.
Among the changes:
- The chunk header has been changed to accomodate the size limitations
encountered on 32-bit architectures. We now fit everything in 64-bit. This
was achieved by storing the amount of unused bytes in an allocation rather
than the size itself, as one can be deduced from the other with the help
of the GetActuallyAllocatedSize function. As it turns out, this header can
be used for both 64 and 32 bit, and as such we dropped the requirement for
the 128-bit compare and exchange instruction support (cmpxchg16b).
- Add 32-bit support for the checksum and the PRNG functions: if the SSE 4.2
instruction set is supported, use the 32-bit CRC32 instruction, and in the
XorShift128, use a 32-bit based state instead of 64-bit.
- Add software support for CRC32: if SSE 4.2 is not supported, fallback on a
software implementation.
- Modify tests that were not 32-bit compliant, and expand them to cover more
allocation and alignment sizes. The random shuffle test has been deactivated
for linux-i386 & linux-i686 as the 32-bit sanitizer allocator doesn't
currently randomize chunks.

[CMake] Add experimental support for building compiler-rt for iOS
Summary:
This is a reunification of three separate reviews D11073, D11082, D11083.
Having them separate was not constructive even though the patches were smaller because it led to fragmented conversations, and this is really all about one change.
This patch incorporates feedback from samsonov, and refactors the hacky darwin code out of the root CMakeLists.txt and int config-ix.cmake.

[Sanitizers, CMake] Basic sanitizer Solaris support (PR 33274)
Summary:
This patch, on top of https://reviews.llvm.org/D40898, contains the build system
changes necessary to enable the Solaris/x86 sanitizer port.
The only issue of note is the libclang_rt.sancov_{begin, end} libraries: clang relies on the
linker automatically defining __start_SECNAME and __stop_SECNAME labels for
sections whose names are valid C identifiers. This is a GNU ld extension not present
in the ELF gABI, also implemented by gold and lld, but not by Solaris ld. To work around
this, I automatically link the sancov_{begin,end} libraries into every executable for now.
There seems to be now way to build individual startup objects like crtbegin.o/crtend.o,
so I've followed the lead of libclang_rt.asan-preinit which also contains just a single
object.

Adding Msan support to FreeBSD
Summary:
Enabling the memory sanitizer support for FreeBSD, most of unit tests are compatible.
- Adding fstat and stressor_r interceptors.
- Updating the struct link_map access since most likely the struct Obj_Entry had been updated since.
- Disabling few unit tests until further work is needed (or we can assume it can work in real world code).

[sanitizer] Initial implementation of a Hardened Allocator
Summary:
This is an initial implementation of a Hardened Allocator based on Sanitizer Common's CombinedAllocator.
It aims at mitigating heap based vulnerabilities by adding several features to the base allocator, while staying relatively fast.
The following were implemented:
- additional consistency checks on the allocation function parameters and on the heap chunks;
- use of checksum protected chunk header, to detect corruption;
- randomness to the allocator base;
- delayed freelist (quarantine), to mitigate use after free and overall determinism.
Additional mitigations are in the works.
