x86: Rename -harden-sls=indirect-branch to -harden-sls=indirect-jmp
Indirect branch also includes indirect call instructions. Rename
-harden-sls=indirect-branch to -harden-sls=indirect-jmp to match its
intended behavior.
PR target/102952
* config/i386/i386-opts.h (harden_sls): Replace
harden_sls_indirect_branch with harden_sls_indirect_jmp.
* config/i386/i386.c (ix86_output_jmp_thunk_or_indirect):
Likewise.
(ix86_output_indirect_jmp): Likewise.
(ix86_output_call_insn): Likewise.
* config/i386/i386.opt: Replace indirect-branch with
indirect-jmp. Replace harden_sls_indirect_branch with
harden_sls_indirect_jmp.
* doc/invoke.texi (-harden-sls=): Replace indirect-branch with
indirect-jmp.
