cd0c94bb - [RISCV] Remove IsEABI from RISCVZC::getStackAdjBase. (#89177)

[RISCV] Remove IsEABI from RISCVZC::getStackAdjBase. (#89177) The usage of IsEABI was only valid for RV32E. For RV64E, the stack adjust base needs to be 32 when ra,s0-s1 are being saved. Since it takes more than 16 bytes to save 3 64-bit registers. The spec lists the rv32e behavior explicitly, but not rv64e. My assumption is that the only thing that changes with rv64e is which registers can be used in the register list, but not how the register list affects the stack_adj_base.
