Nathan Froyd d98002172b Bug 1606625 - don't add PGO flags for wasm compilation; r=rstewart
At the moment, everything we're putting in a wasm sandbox is not
performance-critical, so we don't need PGO.  It's also not clear that
PGO would actually work properly with code that's been run through
wasm.  Let's leave figuring that out until, at the very least, the wasm
toolchain is a little more mature.

# When linking on macOS, debug info is not linked along with the final binary,

# With LTO, object files are temporary, and are not kept around, which
# means there's no object file for dsymutil to do its job. Consequently,
# there is no debug info for LTOed compilation units.
# The macOS linker has however an option to explicitly keep those object
# files, which dsymutil will then find.
# The catch is that the linker uses sequential numbers for those object
# files, and doesn't avoid conflicts from multiple linkers running at
# the same time. So in directories with multiple binaries, object files
# from the first linked binaries would be overwritten by those of the
# last linked binary. So we use a subdirectory containing the name of the
