  1. [CHERI-RISC-V] Baseline test for function entry directives 

    We are emitting the local function symbol alias in a slightly weird
order, which will be fixed in the following commits.

  3. [CHERI] Emit $eh_alias label .type directive in correct location 

    Match the .L<fn>$local: approach and emit it after the symbol.

  4. [CHERI] Reuse the $local function symbol for landing pads 

    There is no need to define our own non-preemptible local symbol since
upstream now has the $local non-preemptible symbol. Since the latest
merge it also includes my upstreamed fixes to always have the right type
and size attributes, so it is safe to use here.

  5. [ELF][CHERI] Rewrite exception-table test in LLVM IR 

    This avoids one dependency on clang and will hopefully allow removing it
entirely soon. Ideally this would be written as an assembly test but
adding the right directives for EH tables is tedious, so I went for
IR instead.

  6. [CHERI] Ensure we always emit the $local symbol for exception handling 

    Without it, we would crash if GV.canBenefitFromLocalAlias() returns
false (e.g. when the function is not dso_local).
