Yeting Kuo	9fb196b469	[RISCV] Insert simple landing pad for taken address labels. (#91855 ) This patch implements simple landing pad labels ([pr]).

This patch also supports option riscv-landing-pad-label to make users cpable to set nonzero fixed labels. Using nonzero fixed label force setting t2 before indirect jumps.

[RISCV] Insert simple landing pad before indirect jumps for Zicfilp. (#91860 )

This patch is based on https://github.com/llvm/llvm-project/pull/91855.
This patch inserts simple landing pad
([pr])before indirct jumps. And this also make option
riscv-landing-pad-label influence this feature.

[RISCV] Insert simple landing pad for taken address labels. (#91855 )

This patch implements simple landing pad labels ([pr]). When Zicfilp
enabled, this patch inserts `lpad 0` at the beginning of basic blocks
which are possible to be landed by indirect jumps.
This patch also supports option riscv-landing-pad-label to make users
cpable to set nonzero fixed labels. Using nonzero fixed label force
setting t2 before indirect jumps. It's less portable but more strict
than original implementation.
