8252237: C2: Call to compute_separating_interferences has wrong argument order

[r-v-raghav]

https://bugs.openjdk.java.net/browse/JDK-8252237

<Copying details from Old PR - https://github.com/openjdk/jdk/pull/1533>
(**NOTE: This old PR was approved then.
But we did not commit the changes then because of last stage of JDK 16
and waited for more tests, performance runs.
Results of multiple test run, performance benchmarks are available now and confirmed no issues)

[src/hotspot/share/opto/coalesce.hpp] -
112 uint compute_separating_interferences(Node *dst_copy, Node *src_copy, Block *b, uint bindex, RegMask &rm, uint rm_size, uint reg_degree, uint lr1, uint lr2);

[src/hotspot/share/opto/coalesce.cpp] -

..........
538 uint PhaseConservativeCoalesce::compute_separating_interferences(Node *dst_copy, Node *src_copy, Block *b, uint bindex, RegMask &rm, uint reg_degree, uint rm_size, uint lr1, uint lr2 ) {
.................
747 reg_degree = compute_separating_interferences(dst_copy, src_copy, b, bindex, rm, rm_size, reg_degree, lr1, lr2 );

So fixing the argument order - [/src/hotspot/share/opto/coalesce.cpp]

-uint PhaseConservativeCoalesce::compute_separating_interferences(Node *dst_copy, Node *src_copy, Block *b, uint bindex, RegMask &rm, uint reg_degree, uint rm_size, uint lr1, uint lr2 ) {
+uint PhaseConservativeCoalesce::compute_separating_interferences(Node *dst_copy, Node *src_copy, Block *b, uint bindex, RegMask &rm, uint rm_size, uint reg_degree, uint lr1, uint lr2 ) {
