Chandler Carruth 2946cd7010 Update the file headers across all of the LLVM projects in the monorepo
to reflect the new license.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Peter Collingbourne c1fde4fa94 sanitizer_common: Change gen_dynamic_list.py to take a -o argument instead of writing to stdout.
This makes the script a little more gn friendly; gn does not support
redirecting the output of a script.

Alex Shlyapnikov 50c342bf3f [Sanitizers] Export aligned new/delete from runtimes.
Summary:
Export aligned new/delete to make dynamic runtimes work again.

Remove all valid new/delete cases from ASan test, there's a test in
common for that.

Kostya Kortchinsky 6edadae34a [sanitizer] Add Scudo to the sanitizer lint checks.
Summary:
Scudo abides by the coding style enforced by the sanitizer_common
linter, but as of right now, it's not linter-enforced.

Add Scudo to the list of directories checked by check_lint.sh.

Also: fixes some linter errors found after getting this running.

Sagar Thakur b1c51f6a94 [ASAN] Use struct instead of array in sancov.py
Summary: When using 32-bit python with 64-bit asan the pc array in sancov.py cannot fit in 64-bit pc's because the type-code 'L' for
arrays in python corresponds to the C type long which is only of 4 bytes. Because of this some of the coverage tool tests fail on
mips. To fix these test possible solutions are to use 64-bit python or use struct.unpack with the 'Q' type-code. We have used
struct.unpack with 'Q' type code since it is not appropriate to have a 64-bit python on all hosts.

Evgeniy Stepanov 567e516015 [asancov] Write coverage directly to a memory-mapped file.
This way does not require a __sanitizer_cov_dump() call. That's
important on Android, where apps can be killed at arbitrary time.

We write raw PCs to disk instead of module offsets; we also write
memory layout to a separate file. This increases dump size by the
factor of 2 on 64-bit systems.

Summary:
Sandboxed code may now pass additional arguments to

single file (the default is one file per module). The user may supply a file or
socket to write to. The latter option can be used to broker out the file writing
functionality. If -1  is passed, we pre-open a file.
