Constified enums are default now. I think I want to introduce an option to
bindgen to allow setting the default enum behavior, but it doesn't need to block
this.
The ServoBindings.toml changes are somewhat hacky, but that's because of
https://github.com/rust-lang-nursery/rust-bindgen/issues/1125.
Also, the fixups now need to account for whitespace, since quote generates stuff
like root :: nsString, and we don't rustfmt the bindings if there's no rustfmt
installed.

This is only slightly more informative because it doesn't give
the filename, but I think it's an improvement on the simple
unwrap() panic when we try to read a file which isn't there.

Bindgen needs some build-specific flags, like the -isysroot
passed to clang for the C++ compilation. Try to read
these from $objdir/layout/style/bindgen.toml which is
created by the Firefox build system, and merge them
into the config.

provide more information when bindgen fails
Providing the flags we passed into clang can be informative for double-checking that we set everything up correctly.

We need another flag that represents allow-negative-number for SMIL, so
this enum will also comprise the another parsing mode that allows negative number.
explicitly specify bitness for x86 cross-compilation situations
Despite compiling for architecture X, the user may have specified a
clang that defaults to architecture Y. We need to ensure that we invoke
clang with the correct architecture selection. We do not use --target
to do this, however, because that runs into problems with LLVM's default
search paths. For the x86 case, we can simply use -m$BITNESS to select
the correct architecture.
This is not at all a general solution, but it does unblock compiling Stylo for 32-bit Linux on Gecko's infra.
