Meta: Make BuildClang.sh produce less output when running in a TTY

Browse source 
Ninja disables its fancy output mode when it's not writing to a TTY.
So don't pipe its output into something else, so that it writes to
a TTY if the invoking terminal is a TTY.

# When ninja writes to a pipe, it strips ANSI escape codes and prints one line per buildstep.
# Instead, use NINJA_STATUS so that we get colored output from LLVM's build and fewer lines of output when running in a tty.
# ANSI escape codes in NINJA_STATUS are slightly janky (ninja thinks that "\e[34m" needs 5 output characters instead of 5, so
# it's middle elision is slightly off; also it would happily elide the "\e39m" which messes up the output if the terminal is too
# narrow), but it's still working better than the alternative.
