Cause the various warnings list to be generated via a <ul> list with
text enclosed in <tt>. This ensures that (a) the text is in a fixed width
font (to indicated generated text) and (b) the text wraps without causing
the page width to be extended. The main result of this is that the report
will wrap to conform to the window size in which it is displayed instead of
having a very wide length if a warning message is long.

improve comments, add a new MVT::getVectorBaseType method.

add another testcase, explicitly check stuff works with G5 and G3 codegen on
PPC.

we don't use lmw/stmw.  When we want them they are easy enough to add

Implement expand of BUILD_VECTOR containing variable elements.
This implements CodeGen/Generic/vector.ll:test_variable_buildvector

fold insertelement(buildvector) -> buildvector if the inserted element # is
a constant.  This implements test_constant_insert in CodeGen/Generic/vector.ll

add two new insert_element tests

implement basic support for INSERT_VECTOR_ELT.

rename these nodes

Rename ConstantVec -> BUILD_VECTOR and VConstant -> VBUILD_VECTOR.  Allow*BUILD_VECTOR to take variable inputs.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26847 91177308-0d34-0410-b5e6-96231b3b80d8

Rename ConstantVec -> BUILD_VECTOR and VConstant -> VBUILD_VECTOR.  Allow
*BUILD_VECTOR to take variable inputs.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26846 91177308-0d34-0410-b5e6-96231b3b80d8

implement vector.ll:test_undef

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26845 91177308-0d34-0410-b5e6-96231b3b80d8

Add three new testcases

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26844 91177308-0d34-0410-b5e6-96231b3b80d8

Fix the remaining bugs in the vector expansion rework I commited yesterday.
This fixes CodeGen/Generic/vector.ll

update testcases for x86 fastcc changes.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26842 91177308-0d34-0410-b5e6-96231b3b80d8

- Fixed a bogus if condition.
- Added more debugging info.
- Allow reuse of IV of negative stride. e.g. -4 stride == 2 * iv of -2 stride.

Change the structure of lowering vector stuff.  Note: This breaks some
things.
