Make sure we correctly set LiveRegGens when a call is unscheduled.  <rdar://problem/10460321>.  No testcase because this is very sensitive to scheduling.

files.  First, add a new block USELIST_BLOCK to the bitcode format.  This is 
where USELIST_CODE_ENTRYs will be stored.  The format of the USELIST_CODE_ENTRYs
have not yet been defined.  Add support in the BitcodeReader for parsing the
USELIST_BLOCK.

When the file isn't being built with subsections-via-symbols, symbol
differences involving non-local symbols can be resolved more aggressively.
Needed for gas compatibility.

Fix a bunch of SSE/AVX patterns to use proper memop types. In particular, not using integer loads other than v2i64/v4i64 since the others are all promoted.

generator to it. For non-bundle instructions, these behave exactly the same
as the MC layer API.

For properties like mayLoad / mayStore, look into the bundle and if any of the
bundled instructions has the property it would return true.
For properties like isPredicable, only return true if *all* of the bundled
instructions have the property.
For properties like canFoldAsLoad, isCompare, conservatively return false for
bundles.

The block offset can be computed from the previous block. That is more
robust than keeping track of a delta.

Data type suffix aliasing. Previously handled via lots of instruction
aliases. Cleanup of those forthcoming.
