6af531febe Introduce DebugInfoProbe. This is used to monitor how llvm optimizer is treating debugging information. 
It generates output that lools like

8 times line number info lost by Scalar Replacement of Aggregates (SSAUp) 
1 times line number info lost by Simplify well-known library calls 
12 times variable info lost by Jump Threading

conventions to be properly printed when emitted in text form.

d01f50f42c ConstantInt has some getters which return ConstantInt's or ConstantVector's of 
the value splatted into every element. Extend this to getTrue and getFalse which
by providing new overloads that take Types that are either i1 or <N x i1>. Use
it in InstCombine to add vector support to some code, fixing PR8469!

38c4e53549 Add a special streamer to libLTO that just records symbols definitions and 
uses.

The result produced by the streamer is used to give the linker more accurate
information and to add to llvm.compiler.used. The second improvement removes
the need for the user to add __attribute__((used)) to functions only used in
inline asm. The first one lets us build firefox with LTO on Darwin :-)

bc53ca1b53 Fix a regression from r125393; 
It caused a crash in MultiSource/Benchmarks/Bullet.
Opt hit an assertion with "opt -std-compile-opts" because
Constant::getAllOnesValue doesn't know how to handle floats.

This patch added a test to reproduce the problem and a check that the
destination vector is of integer type.

Thank you Benjamin!

types in the LangRef and zero vectors are stored as ConstantAggregateZero.
