bf5427a7f0 Move isIdentifiedObject and isNoAliasCall into AliasAnalysis.cpp since 
they are useful to analyses other than BasicAliasAnalysis.cpp. Include
the full comment for isIdentifiedObject in the header file. Thanks to
Chris for suggeseting this.

what it is, but we do want the alloca promoted.

created. Specifically, those BuildMIs which use
"DebugLoc::getUnknownLoc()". I'll remove them soon.

7b176db971 Add explicit -march=x86 to these tests so that they don't 
default to -march=x86-64 on 64-bit hosts.

0103631cce Use the SubclassData field to hold ExtType, isTrunc, and MemIndexedMode 
information. This eliminates the need for the Flags field in MemSDNode,
so this makes LoadSDNode and StoreSDNode smaller. Also, it makes
FoldingSetNodeIDs for loads and stores two AddIntegers smaller.

2170150035 Change Feature64Bit to not imply FeatureSSE2. All x86-64 hardware has 
SSE2, however it's possible to disable SSE2, and the subtarget support
code thinks that if 64-bit implies SSE2 and SSE2 is disabled then
64-bit should also be disabled. Instead, just mark all the 64-bit
subtargets as explicitly supporting SSE2.

Also, move the code that makes -march=x86-64 enable 64-bit support by
default to only apply when there is no explicit subtarget. If you
need to specify a subtarget and you want 64-bit code, you'll need to
select a subtarget that supports 64-bit code.

9d2293f7ad MergeValueInto is too smart: it might choose to do the merge the opposite direction. 
Live interval reconstruction needs to account for this, and scour its maps to
prevent dangling references.
