fbe36ad68a Revert "Use CachingSourceMapView::byte_pos_to_line_and_col instead of SourceMap::lookup_char_pos"
This reverts commit eb4fc45310.

It caused a panic while compiling simple-raytracer

eb4fc45310 Use CachingSourceMapView::byte_pos_to_line_and_col instead of SourceMap::lookup_char_pos
The former calculates byte offsets instead of char offsets. It is faster
to calculate byte offsets than char offsets. Also most DWARF producers
and consumers use byte offsets instead of char offsets.

33e73091f8 Don't mark unwind ebbs as cold
This fixes the code_layout optimization, as it would previously try to
move non-existing ebbs.

Fixes #877

a288a5ea06 Store nightly snapshot in rust-toolchain file, and use it in cargo.sh
The rust-toolchain file can also store an exact nightly snapshot
(instead of just "nightly"), so we can store whatever snapshot that
rustc_codegen_cranelift is known to work with.

This also lets us add a new feature to `cargo.sh` to let it use the
exact same nightly snapshot as cg_clif.  If there's a nightly compiler
mismatch, you get a confusing error message like:

    error: couldn't load codegen backend "librustc_codegen_cranelift.so":
    "librustc_driver-681e2b4f66c73d3e.so: cannot open
    shared object file: No such file or directory"

So doing this automatically in cargo.sh is useful.
