[PATCH] tcg: Extend call args using the correct opcodes

[Richard Henderson]

Pretending that the source is i64 when it is in fact i32 is
incorrect; we have type-changing opcodes that must be used.
This bug trips up the subsequent change to the optimizer.

This fixes a problem found in s390x host testing, and should
be considered patch 41.5/51 in
