Petr Hosek 5668d83e0e [Driver] Make the use of relax relocations a per target option
The support for relax relocations is dependent on the linker and
different toolchains within the same compiler can be using different
linkers some of which may or may not support relax relocations.

Give toolchains the option to control whether they want to use relax
relocations in addition to the existing (global) build system option.

Petr Hosek 3e199ecdad [Driver] Use ld.lld directly for Fuchsia rather than passing flavor
Passing a flavor to LLD requires command line argument, but if these
are being passed through a response file, this will fail because LLD
needs to know which driver to use before processing the response file.
Use ld.lld directly instead to avoid this issue.

Petr Hosek e63da24f57 [Driver] Fuchsia targets default to -fasynchronous-unwind-tables
This regressed for x86-64 in r307856 because it's no longer inherited
from Generic_GCC. We'd never noticed that it was missing other
targets (i.e. aarch64), but Fuchsia is uniform across all machines.

Petr Hosek 83214dfb01 [Driver][Fuchsia] Pass --hash-style=gnu to the linker
The .gnu_hash format is superior, and all versions of the Fuchsia
dynamic linker support it.

Petr Hosek cc24851da6 Reland "[Driver] Update Fuchsia driver path handling"
Several improvements to the Fuchsia driver:

* Search for C++ library headers and libraries in directories that
are part of the toolchain distribution rather than sysroot.

* Use LLVM support utlities to construct paths to make sure the driver
is also usable on Windows for cross-compiling.

* Change the driver to inherit directly from ToolChain rather than
Generic_GCC since we don't need any of the GCC related multilib logic.

Petr Hosek 62e1d23986 [Driver] Add driver support for Fuchsia
Provide toolchain and tool support for Fuchsia operating system.
Fuchsia uses compiler-rt as the runtime library and libc++, libc++abi
and libunwind as the C++ standard library. lld is used as a default
linker.
