26c6e3ba7d when opt crashes, print its command line arguments as a pretty stack trace. 
Somehow opt was missed when this was added.

2d7d4fb9a6 Put a threshold on the number of users PointerMayBeCaptured 
examines; fall back to a conservative answer if there are
more. This works around some several compile time problems
resulting from BasicAliasAnalysis calling PointerMayBeCaptured.

The value has been chosen arbitrarily.

This fixes rdar://7438917 and may partially address PR5708.

d673b32280 Clean up dead operands left around after SROA replaces a mem intrinsic. 
I'm not aware that this does anything significant on its own, but it's
needed for another patch that I'm working on.

7c94e1aa2a For VC++, define the ?INT*_C macros only it they are not yet defined. 
Some compatibility updates like the Boost TR1 compatibility headers
define them.

2a16652946 Introduce the "@llvm.dbg.value" debug intrinsic. 
The semantics of llvm.dbg.value are that starting from where it is executed, an offset into the specified user source variable is specified to get a new value.

An example:
  call void @llvm.dbg.value(metadata !{ i32 7 }, i64 0, metadata !2)
Here the user source variable associated with metadata #2 gets the value "i32 7" at offset 0.
