LegalizeDAG.cpp. Unlike the code it replaces, which simply decrements the simple
type by one, getHalfSizedIntegerVT() searches for the smallest simple integer
type that is at least half the size of the type it is called on. This approach
has the advantage that it will continue working if a new value type (such as
i24) is added to MVT.

Also, in preparation for new value types, remove the assertions that
non-power-of-2 8-bit-mutiple types are Extended when legalizing extload and
truncstore operations.

Convert GRExprEngine::VisitCallExpr() to use a worklist instead of recursion to evaluate the arguments of a CallExpr.  This simplifies the logic and makes it easier to read.  (it also avoids any issues with blowing out the stack if the CallExpr had a ridiculous number of arguments)

Patch from jon.forums at gmail.com

llvm-svn: 91603

incrementing the simple value type of the 16-bit type, which would give the
wrong type if an intemediate MVT (such as i24) were introduced.

implement PR3962: diagnose more faulty cases of usage of the restrict qualifier. this also removes a FIXME

revert part of my last patch, and mark only the c++ global new operator as noalias. the rest will be infered by llvm optz

Revert 91280-91283, 91286-91289, 91291, 91293, 91295-91296. It apparently introduced a non-deterministic behavior in the optimizer somewhere.

Rename GetAddrOfRTTI to GetAddrOfRTTIDescriptor. Remove the overload that takes a CXXRecordDecl since we were just creating a QualType from it anyway.

1. Don't make a copy of LangOptions every time a lexer is created.
2. Don't make CharInfo global mutable state.
3. Fix the implementation to properly treat ^Z as EOF instead of as
   horizontal whitespace, which matches the semantic implemented by VC++.

with -disassemble, llvm-mc now accepts lines of the
form
0x00 0x00
and passes the resulting bytes to the disassembler for
the chosen (or default) target, printing the result.

Fold (zext (and x, cst)) -> (and (zext x), cst)

DAG combiner likes to optimize expression in the other way so this would end up cause an infinite looping.
