Summary:
The purpose of this option is provide a way for the ASan dylib
to be loaded via `dlopen()` without triggering most initialization
steps (e.g. shadow memory set up) that normally occur when the
ASan dylib is loaded.
This new functionality is exposed by
- A `SANITIZER_SUPPORTS_INIT_FOR_DLOPEN` macro which indicates if the
feature is supported. This only true for Darwin currently.
- A `HandleDlopenInit()` function which should return true if the library
is being loaded via `dlopen()` and
`SANITIZER_SUPPORTS_INIT_FOR_DLOPEN` is supported. Platforms that
support this may perform any initialization they wish inside this
function.
Although disabling initialization is something that could potentially
apply to other sanitizers it appears to be unnecessary for other
sanitizers so this patch only makes the change for ASan.

Summary:
In order for this test to work the log file needs to be removed from both
from the host and device. To fix this the `rm` `RUN` lines have been
replaced with `RUN: rm` followed by `RUN: %device_rm`.
Initially I tried having it so that `RUN: %run rm` implicitly runs `rm`
on the host as well so that only one `RUN` line is needed. This
simplified writing the test however that had two large drawbacks.
* It's potentially very confusing (e.g. for use of the device scripts outside
of the lit tests) if asking for `rm` to run on device also causes files
on the host to be deleted.
* This doesn't work well with the glob patterns used in the test.
The host shell expands the `%t.log.*` glob pattern and not on the
device so we could easily miss deleting old log files from previous
test runs if the corresponding file doesn't exist on the host.
So instead deletion of files on the device and host are explicitly
separate commands.
The command to delete files from a device is provided by a new
substitution `%device_rm` as suggested by Filipe Cabecinhas.
The semantics of `%device_rm` are that:
* It provides a way remove files from a target device when
the host is not the same as the target. In the case that the
host and target are the same it is a no-op.
* It interprets shell glob patterns in the context of the device
file system instead of the host file system.
This solves the globbing problem provided the argument is quoted so
that lit's underlying shell doesn't try to expand the glob pattern.
* It supports the `-r` and `-f` flags of the `rm` command,
with the same semantics.
Right now an implementation of `%device_rm` is provided only for
ios devices. For all other devices a lit warning is emitted and
the `%device_rm` is treated as a no-op. This done to avoid changing
the behaviour for other device types but leaves room for others
to implement `%device_rm`.
The ios device implementation uses the `%run` wrapper to do the work
of removing files on a device.
The `iossim_run.py` script has been fixed so that it just runs `rm`
on the host operating system because the device and host file system
are the same.

Summary:
Original patch by Kuba Mracek
The %T lit expansion expands to a common directory shared between all
the tests in the same directory, which is unexpected and unintuitive,
and more importantly, it's been a source of subtle race conditions and
flaky tests. In https://reviews.llvm.org/D35396, it was agreed that it
would be best to simply ban %T and only keep %t, which is unique to each
test. When a test needs a temporary directory, it can just create one
using mkdir %t.
This patch removes %T in compiler-rt.
