[LLVMdev] LLVM DebugInfoBuilder

[Talin]

Looking at DebugInfo.h, there are a couple of minor features that
DebugInfoBuilder that I would miss:
1) The ability to pass in an LLVM type and have it figure out the size,
alignment, etc. without having to explicitly pass those values in as
parameters to the builder call.

2) The ability for the size & alignment to be specified as Constants rather
than as int64 so that the "gep trick" can be used to generate
target-agnostic debug info. (I don't know if there are other aspects of the
debug info which would prevent it from being target-agnostic.)
