The build process has changed somewhat since switching to host fuzzing
mode. Also, rearrange the fx build steps earlier, since they're a
prerequisite for building syzkaller.
Enables the syntax intN[start:end, alignment] for integer ranges. For
instance, int32[0:10, 2] represents even 32-bit numbers between 0 and 10
included. With this change, two NEED tags in syscall descriptions can be
addressed.

This commit removes a dependency on fuchsia's tools/devshell/contrib/go,
which was removed recently[0].
Now to build go binaries for fuchsia we are not relying on the
fuchsia.git repo at all. The code just needs a copy of the fuchsia
//third_party/go repository, the fuchsia sdk and a copy of clang.
Users should download the sdk and clang beforehand (see documentation
for links), and then run (with the correct environment variables):
```
$ make TARGETOS=fuchsia TARGETARCH=amd64 \
SOURCEDIR=$HOME/fuchsia \
FX_SDK_PATH=${HOME}/sdk/fuchsia-sdk \
CLANG_PATH=${HOME}/sdk/clang \
fuchsia_go
```
After that, they will be able to build the syzkaller go binaries by
doing:
```
$ make TARGETOS=fuchsia TARGETARCH=amd64 \
SOURCEDIR=$HOME/fuchsia \
FX_SDK_PATH=${HOME}/sdk/fuchsia-sdk \
CLANG_PATH=${HOME}/sdk/clang
```
This commits adds two scripts to tools/fuchsia, one for building go in
fuchsia (just calls the ./make.all script in fuchsia's go repo), and one
that replaces the devshell/contrib/go script.
Given that go is unsupported in fuchsia, this change might break at any
point.

In the various linux build instructions, add pointers to the main
doc with instructions for building syzkaller.
These instructions were present before commit d23e90a7b44b ("all:
switch to Go 1.12"). They were duplicated across files. Since the
commit the instructions are in one place. Make it easier to find
them from the platform-specific setup guides.
Also clarify in the x86_64 guide that using a precompiled compiler
from the supplied list is optional if the distribution provided
compiler is recent enough. Before commit d28f4ce ("Update
setup_ubuntu-host_qemu-vm_x86-64-kernel.md") the file had explicit
build instructions. Those are no longer needed.
The sneaky '“' character causes errors when copy-pasting snapshots of
the documentation.
Solved with s/“/"/g.
