bb975d9dcb Update the documentation on "How to Release LLVM". It lays out a new way of 
tagging and branching for the release. I will update this more throughout the
2.9 release process.

ab7cf630f4 Enable support for vector sext and trunc: 
Limit the folding of any_ext and sext  into the load operation to scalars.
Limit the active-bits trunc optimization to scalars.
Document vector trunc and vector sext in LangRef.

Similar to commit 126080 (for enabling zext).

1660c0bc25 Fix 9267; Add vector zext support. 
The DAGCombiner folds the zext into complex load instructions. This patch
prevents this optimization on vectors since none of the supported targets
knows how to perform load+vector_zext in one instruction.

aaec1aa6b6 Don't document exactly how virtual registers are represented as integers. Code 
shouldn't depend directly on that.

Give an example of how to iterate over all virtual registers in a function
without depending on the representation.

9f526bcf4d First step in fixing PR8927: 
Add a unnamed_addr bit to global variables and functions. This will be used
to indicate that the address is not significant and therefore the constant
or function can be merged with others.

If an optimization pass can show that an address is not used, it can set this.

Examples of things that can have this set by the FE are globals created to
hold string literals and C++ constructors.

Adding unnamed_addr to a non-const global should have no effect unless
an optimization can transform that global into a constant.

Aliases are not allowed to have unnamed_addr since I couldn't figure
out any use for it.

a52e5dbdfa Stub out a new updating interface to AliasAnalysis, allowing stateful analyses to be informed when 
a pointer value has potentially become escaping.  Implementations can choose to either fall back to
conservative responses for that value, or may recompute their analysis to accomodate the change.

a8e288b52d Further expand what a call graph pass may do. 
The rationale is that after analyzing a function in the SCC, we may want to
modify it in a way that requires us to update its uses (f.e. to replace the
call with a constant) or its users (f.e. to call it with fewer arguments).

28140b5288 Fix PR 8199. This patch prepends the build tool dir to LLVM programs 
being tested.  This ensures that we test the tools just built and not
some random tools that might happen to be in the user's PATH.  This
makes LLVM testing much more stable and predictable.
