specified at Command creation, rather than as part of the Tool.
This resolves the hack I just added to allow Darwin toolchain to vary
its level of support based on `-mlinker-version=`.
The change preserves the _current_ settings for response-file support.
Some tools look likely to be declaring that they don't support
response files in error, however I kept them as-is in order for this
change to be a simple refactoring.

Summary:
The Android NDK's clang driver is used with an Android -target setting,
and the driver automatically finds the Android sysroot at a path
relative to the driver. The sysroot has the libc++ headers in it.
Remove Hurd::computeSysRoot as it is equivalent to the new
ToolChain::computeSysRoot method.
Fixes PR46213.

If a GCC installation is not detected, then this attempts to
use compiler-rt and the compiler-rt crtbegin/crtend
implementations as a fallback.

This started passing target-features on the linker line, not just for RISCV but
for all targets, leading to error messages in Chromium Android build:
'+soft-float-abi' is not a recognized feature for this target (ignoring feature)
'+soft-float-abi' is not a recognized feature for this target (ignoring feature)
See Phabricator review for details.
Reverting until this can be fixed properly.

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.

The darwin linker was complaining about Toolchains/RISCV.cpp and
Toolchains/Arch/RISCV.cpp had the same name. Fix is to just rename
Toolchains/RISCV.cpp to Toolchains/RISCVToolchain.cpp.
