Fixes dotnet#95367. Relevant part of the JitDump: ``` Using `if true` assertions from pred BB02 Assertions in: #1 fgMorphTree BB04, STMT00021 (before) [000070] DA--------- * STORE_LCL_VAR ubyte V10 tmp9 [000057] ----------- \--* CAST int <- ubyte <- int [000006] ----------- \--* EQ int [000004] ----------- +--* LCL_VAR ref V02 tmp1 (last use) [000055] H---------- \--* CNS_INT(h) ref 'Frozen EmptyPartition`1<Int32> object' Assertion prop for index #1 in BB04: [000006] ----------- * EQ int GenTreeNode creates assertion: [000070] DA---+----- * STORE_LCL_VAR ubyte V10 tmp9 In BB04 New Local Constant Assertion: V10 == [0000000000000001], index = #2 fgMorphTree BB04, STMT00021 (after) [000070] DA---+----- * STORE_LCL_VAR ubyte V10 tmp9 [000055] H----+----- \--* CNS_INT(h) int ``` The JitDump is unfinished because the compiler crashes when trying to dump the last line. Clearly, the `CNS_INT` is no longer a handle at that point because we just bashed it to a constant 1.
