Apply size optimizations to panic machinery and some cold functions * std dependencies gimli and addr2line are now built with opt-level=s * various panic-related methods and `#[cold]` methods are now marked `#[optimize(size)]` Panics should be cold enough that it doesn't make sense to optimize them for speed. The only tradeoff here is if someone does a lot of backtrace captures (without panics) and printing then the opt-level change might impact their perf. Seems to be the first use of the optimize attribute. Tracking issue #54882

# For compiler-builtins we always use a high number of codegen units.
|
|
# The goal here is to place every single intrinsic into its own object
|
|
# file to avoid symbol clashes with the system libgcc if possible. Note
|
|
# that this number doesn't actually produce this many object files, we
|
|
# just don't create more than this number of object files.
|
|
#
|
|
# It's a bit of a bummer that we have to pass this here, unfortunately.
|
|
# Ideally this would be specified through an env var to Cargo so Cargo
|
|
# knows how many CGUs are for this specific crate, but for now
|
|
# per-crate configuration isn't specifiable in the environment.

# These dependencies of the standard library implement symbolication for

|
# backtraces on most platforms. Their debuginfo causes both linking to be slower
|
|
# (more data to chew through) and binaries to be larger without really all that
|
|
# much benefit. This section turns them all to down to have no debuginfo which
|
|
# helps to improve link times a little bit.
