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.

-Allow it to be used with multiple BeginSourceFile/EndSourceFile calls; for this introduce
 a "finish" callback method in the DiagnosticConsumer. SDiagsWriter finishes up the serialization
 file inside this method.
-Make it independent of any particular DiagnosticsEngine; make it use the SourceManager of the
 Diagnostic object.
-Ignore null source ranges.

The block offset can be computed from the previous block. That is more

when we load a module map (module.map) from a directory, also load a
private module map (module_private.map) for that directory, if
present. That private module map can inject a new submodule that
captures private headers.

This flag is used when bundling machine instructions.  It indicates
whether the operand reads a value defined inside or outside its bundle.

- Remove unused types/fields.
- Add some constantness.

llvm-svn: 145993

For example, ARM allows:
    vmov.u32 s4, #0  -> vmov.i32, #0
'u32' is a more specific designator for the 32-bit integer type specifier
and is legal for any instruction which accepts 'i32' as a datatype suffix.

We want to say,
    def : TokenAlias<".u32", ".i32">;

This works by marking the match class of 'From' as a subclass of the
match class of 'To'.
