ipa/100513 - fix SSA_NAME_DEF_STMT corruption in IPA param manip

This fixes unintended clobbering of SSA_NAME_DEF_STMT of the
cloned/inlined from SSA name during IPA parameter manipulation
of call stmt LHSs.  gimple_call_set_lhs adjusts SSA_NAME_DEF_STMT
of the lhs to the stmt being modified but when
ipa_param_body_adjustments::modify_call_stmt is called the
cloning/inlining process has not yet remapped the stmts operands
to the copy variants but they are still original.

* ipa-param-manipulation.c
(ipa_param_body_adjustments::modify_call_stmt): Avoid
altering SSA_NAME_DEF_STMT by adjusting the calls LHS
via gimple_call_lhs_ptr.

I see this also on a go build on raspberry pi. Interesting.

Yes, this was reported by Maxim as well, independent of this
patch.  It's caused by sth else.

When build the go on trunk with the patch, an error occur:
In function 'syscall.forkExec':

Yes, with the patch, bootstrap-O3 pass on ppc64le too.

Thanks!

Fixed on trunk sofar.  The same code is present on the GCC 10 branch but not
literally on the GCC 9 branch.
