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.
