Even though rusticl won't advertise support for 64 bit ints, some of the
libclc builtins still use 64 bit operations to lower 32 bit ALU ops.

Previously, the register demand per instruction was calculated as the number of
live variables in the register file after executing an instruction plus additional
temporary registers, necessary during the execution of the instruction.
With this change, now it also includes all variables which are live right before
executing an instruction, i.e. killed Operands.
Care has been taken so that the invariant
register_demand[idx] = register_demand[idx - 1] - get_temp_registers(prev_instr)
+ get_live_changes(instr) + get_temp_registers(instr)
still holds.

The ISL_AUX_USAGE_STC_CCS is the last defined usage. We could
get a random value from isl_encode_aux_mode[] once it is passed
as index if its element is not initialized.
Explicit initialization of ISL_AUX_USAGE_HIZ_CCS_WT is added too.

The two cases can pass if we run them respectively. But once they
are fed to glcts in a test case list file (test.list) to run together,
the second test case hangs for a while and eventually fails, regardless
which of them is the second.

The texturing and rendering preparation functions restrict
fast clear support in some cases to account for limitations
on prior platforms. Instead of updating those checks to avoid
resolves on Xe2, we can bypass them by representing the aux
state of a fast-cleared surface as compressed-no-clear. This
is valid because there is no longer a bit pattern which
references a clear value stored outside of the aux surface.
