of void type, to ensure that we can still fold ((void)0, 1) as an array bound.

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

No functional change yet. Will be implementing range-checked immediates
for better diagnostics and disambiguation of instructions.

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

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'.

 - Created a new SymExpr type - SymbolCast.
 - SymbolCast is created when we don't know how to simplify a NonLoc to
NonLoc casts.
 - A bit of code refactoring: introduced dispatchCast to have better
code reuse, remove a goto.
 - Updated the test case to showcase the new taint flow.

evaluator into constant initializer handling / IRGen. The practical consequence
of this is that the bitcast now lives in the constant's definition, rather than
in its uses.

The code in the constant expression evaluator was producing vectors of the wrong
type and size (and possibly of the wrong value for a big-endian int-to-vector
bitcast). We were getting away with this only because we don't yet support
constant-folding of any expressions which inspect vector values.

3. Changed MachineBasicBlock iterator to skip over bundled MIs; added an iterator to walk all the MIs
4. Taught MachineBasicBlock methods about bundled MIs

- Exposes a CXType_Vector type kind for vector types.
- Adds generalized versions of the clang_getArrayElementType and clang_getArraySize functions, named clang_getElementType and clang_getNumElements, which work on array, vector, or complex types.
- Adds additional functions for querying function types. clang_isFunctionTypeVariadic returns true if a function type is variadic. clang_getFunctionCallingConv returns an enumeration value indicating the calling convention of the function type. clang_getNumArgTypes returns the number of static argument types, and clang_getArgType gets the type of an argument.
- Adds a clang_getTypedefDeclUnderlyingType function to get the underlying type from a TypedefDecl cursor.
- Adds a clang_getEnumDeclIntegerType function to get the integer type from an EnumDecl cursor.
- Adds clang_getEnumConstantDeclValue and clang_getEnumConstantDeclUnsignedValue functions to get the value of an EnumConstantDecl as a signed or unsigned long long, respectively.
- Exposes a CXCursor_AsmLabelAttr cursor kind for __asm__("label") attributes.
- Alters clang_getCursorSpelling to return the label value for AsmLabelAttr-kind cursors.

This pseudo-instruction contains a .align directive in its expansion, so
the total size may vary by 2 bytes.

It is too difficult to accurately keep track of this alignment
directive, just use the worst-case size instead.

ARMConstantIslandPass may sometimes leave empty constant islands behind
(it really shouldn't). Remove the alignment from the empty islands so
the size calculations are still correct.

This should fix the many Thumb1 assembler errors in the nightly test
suite.

The reduced test case for this problem is way too big. That is to be
expected for ARMConstantIslandPass bugs.
