d47d348cdf It's possible for a global variable to be optimized out of a metadata object. So 
we should allow a "null" with this dyn_cast.

bd50ec69e4 Move the dominator verification code out of special code embedded within 
the PassManager code into a regular verifyAnalysis method.

Also, reorganize loop verification. Make the LoopPass infrastructure
call verifyLoop as needed instead of having LoopInfo::verifyAnalysis
check every loop in the function after each looop pass. Add a new
command-line argument, -verify-loop-info, to enable the expensive
full checking.

205b641954 Change tests from "opt %s" to "opt < %s" so that opt doesn't see the 
input filename so that opt doesn't print the input filename in the

strings in the input filename.

7d42bfab6c 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!)

bcc1187643 llvm.dbg.region.end() intrinsic is not required to be in _last_ basic block in a function. If that happens then any basic block that follows (lexically) the block with regin.end will not have scope info available. LexicalScopeStack relies on processing basic block in CFG order, but this processing order is not guaranteed. Things get complicated when the optimizer gets a chance to optimizer IR with dbg intrinsics. 
Apply defensive patch to preserve at least one lexical scope till the end of function.

35584a26be Move the bookkeeping of the debug scopes back to the place where it 
belonged. The variable declaration stuff wasn't happy with it where it
was. Sorry that the testcase is so big. Bugpoint wasn't able to reduce it
successfully.

7546bed590 Second attempt: 
Massive check in. This changes the "-fast" flag to "-O#" in llc. If you want to
use the old behavior, the flag is -O0. This change allows for finer-grained
control over which optimizations are run at different -O levels.

Most of this work was pretty mechanical. The majority of the fixes came from
verifying that a "fast" variable wasn't used anymore. The JIT still uses a
"Fast" flag. I'll change the JIT with a follow-up patch.

3324e1f491 Global variables don't have a corresponding llvm.dbg.declare, yet it is possible 
to obtain debug info about them.
Introduce helpers to access debug info for global variables. Also introduce a
helper that works for both local and global variables.

ceed180d4c When removing a store to an alloca that has only one 
use, check also for the case where it has two uses,
the other being a llvm.dbg.declare.  This is needed so
debug info doesn't affect codegen.
