[AArch64] Combine PTEST_FIRST(PTRUE, CONCAT(A, B)) -> PTEST_FIRST(PTRUE, A) (#161384)
When the input to ptest_first is a vector concat and the mask is all active,
performPTestFirstCombine returns a ptest_first using the first operand
of the concat, looking through any reinterpret casts.
This allows optimizePTestInstr to later remove the ptest when the first
operand is a flag setting instruction such as whilelo.
