Jakob Sinclair 7606854f43 pan/compiler: fix spilling for 64-bit values
For the BIR-compiler, 64-bit values were not properly tracked in the
spill logic and PHIs were always assumed to be 32-bits. This could
create issues were only one half of the value was reloaded or spills
would overlap each other leading to garbage values. This patch fixes
these issues by keeping track of how many words each value needs. Also,
it adds a constraint for SHADD sources where it splits and collects them
right before the SHADD instruction itself to make it easier for RA to
handle the register pairs.

Fixes: 4542982062 ("pan/compiler: Use SHADDX instruction for i64 add")
