combine: Allow combining two insns to two insns
This patch allows combine to combine two insns into two. This helps
in many cases, by reducing instruction path length, and also allowing
further combinations to happen. PR85160 is a typical example of code
that it can improve.
This patch does not allow such combinations if either of the original
instructions was a simple move instruction. In those cases combining
the two instructions increases register pressure without improving the
code. With this move test register pressure does no longer increase
noticably as far as I can tell.
(At first I also didn't allow either of the resulting insns to be a
move instruction. But that is actually a very good thing to have, as
should have been obvious).

lra: consider clobbers when selecting hard_regno to spill
The idea behind the rclass loop in spill_hard_reg_in_range() seems to
be: find a hard_regno, which in general conflicts with reload regno,
but does not do so between `from` and `to`, and then do the live range
splitting based on this information. To check the absence of conflicts,
we make use of insn_bitmap, which does not contain insns which clobber
the hard_regno.

libsanitizer: Mark REAL(swapcontext) with indirect_return attribute on x86
Cherry-pick compiler-rt revision 337603:
When shadow stack from Intel CET is enabled, the first instruction of all
indirect branch targets must be a special instruction, ENDBR.
lib/asan/asan_interceptors.cc has
...
int res = REAL(swapcontext)(oucp, ucp);
...
REAL(swapcontext) is a function pointer to swapcontext in libc. Since
swapcontext may return via indirect branch on x86 when shadow stack is
enabled, as in this case,
int res = REAL(swapcontext)(oucp, ucp);
^^^^^^^^^^^^^^^^^^^^^^^^^^^^ This function may be
returned via an indirect branch.
Here compiler must insert ENDBR after call, like
call *bar(%rip)
endbr64
I opened an LLVM bug:
https://bugs.llvm.org/show_bug.cgi?id=38207
to add the indirect_return attribute so that it can be used to inform
compiler to insert ENDBR after REAL(swapcontext) call. We mark
REAL(swapcontext) with the indirect_return attribute if it is available.
This fixed:
