041de42d42 Don't assume that two identical instructions that read from memory 
will always return the same value. This isn't currently necessary,
since this code doesn't currently ever get called under circumstances
where it would matter, but it may some day.

baa26395cc Make LLVM command-line tools overwrite their output files without -f. 
This is conventional command-line tool behavior. -f now just means
"enable binary output on terminals".

Add a -f option to llvm-extract and llvm-link, for consistency.

Remove F_Force from raw_fd_ostream and enable overwriting and
truncating by default. Introduce an F_Excl flag to permit users to
enable a failure when the file already exists. This flag is
currently unused.

Update Makefiles and documentation accordingly.

2a610c7387 Update DebugInfo interface to use metadata, instead of special named llvm.dbg.... global variables, to encode debugging information in llvm IR. This is mostly a mechanical change that tests metadata support very well. 
This change speeds up llvm-gcc by more then 6% at "-O0 -g" (measured by compiling InstructionCombining.cpp!)

96135b617a This patch cleans up the ProfileInfo by 
*) introducing new data type and export function of edge info for whole function (preparation for next patch).
*) renaming variables to make clear distinction between data and containers that contain this data.
*) updated comments and whitespaces.
*) made ProfileInfo::MissingValue a double (as it should be...).

(Discussed at http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20090817/084955.html.)

3d01334e6f Fix a bug in the over-index constant folding. When over-indexing an 
array member of a struct, it's possible to land in an arbitrary position
inside that struct, such that attempting to find further getelementptr
indices will fail. In such cases, folding cannot be done.

de0e587e63 Canonicalize indices in a constantexpr GEP. If Indices exceed the 
static extents of the static array type, it causes GlobalOpt and
other passes to be more conservative. This canonicalization also
allows the constant folder to add "inbounds" to GEPs.

699db99c1a SIV/MIV classification for LDA. 
LoopDependenceAnalysis::getLoops is currently O(N*M) for a loop-nest of
depth N and a compound SCEV of M atomic SCEVs. As both N and M will
typically be very small, this should not be a problem. If it turns out
to be one, rewriting getLoops as SCEVVisitor will reduce complexity to
O(M).
