re PR bootstrap/53021 (bootstrap failure on Linux/ia32)
PR bootstrap/53021
* alias.h (UNIQUE_BASE_VALUE_SP, UNIQUE_BASE_VALUE_ARGP,
UNIQUE_BASE_VALUE_FP, UNIQUE_BASE_VALUE_HFP): Define.
* alias.c (init_alias_targets): Use UNIQUE_BASE_VALUE_*
macros instead of constants.
* dse.c (record_store): Check for SP ADDRESS by comparing
XWINT to UNIQUE_BASE_VALUE_SP instead of expecting
XEXP to be stack_pointer_rtx.
