There is no way to tell in spirv_compiler_emit_load_reg() if the write
mask is 64-bit. All loads are 32-bit except for IMMCONST64 and SSA, and
the latter ignores the mask, so the only issue lies with IMMCONST64.
I realized that it is better to lower casts to int to FLOOR+REINTERPET
instead of appending a FLOOR to all casts to int and assuming that this
is the case for all of them in d3dbc.c.
This in case we introduce new passes in the future that add casts that
we forget to lower, after the lower_casts_to_bool pass.
Like we did before commit 6d4782ed7f7e06cff31313c3170ea5e6bc281254. That
commit somehow managed to change the "desc" field from
D3D12_RESOURCE_DESC to D3D12_RESOURCE_DESC1, but that breaks the ABI.

macOS tigetstr() takes a non-const char *, so account for that as well.
