tcg/optimize: fix uninitialized variable
The variables uext_opc and sext_opc are used without initialization if
TCG_TARGET_extract_i{32,64}_valid returns false. The result, depending
on the compiler, might be the generation of extract and sextract opcodes
with invalid offset and count, or just random data in the TCG opcode
stream.
Fixes: ceb9ee06b71 ("tcg/optimize: Handle TCG_COND_TST{EQ,NE}", 2024-02-03)
