Consider address spaces for hashing and CSEing DAG nodes. Otherwise two loads from different x86 segments but the same address would get CSEd

Fix an inconsistency in the x86 backend that led it to reject "calll foo" on
...
x86-32: 32-bit calls were named "call" not "calll". 64-bit calls were correctly
named "callq", so this only impacted x86-32.
This fixes rdar://8456370 - llvm-mc rejects 'calll'
This also exposes that mingw/64 is generating a 32-bit call instead of a 64-bit call,
I will file a bugzilla.

linux has a different stack alignment than the mac, relax this a bit.

For now, just disable folding the load into the call.
