One case in BranchRelaxation did not compute liveins after creating a
new block. This is catched by existing tests with an upcoming commit
that will improve MachineVerifier checking of livein lists.

Re-commit r303937 + r303949 as they were not the cause for the build
failures.
We do not track liveness of reserved registers so adding them to the
liveins list in computeLiveIns() was completely unnecessary.

Tentatively revert, suspecting that it caused breakage in stage2
buildbots.
This reverts commit r303949.
This reverts commit r303937.

We had various variants of defining dump() functions in LLVM. Normalize
them (this should just consistently implement the things discussed in
http://lists.llvm.org/pipermail/cfe-dev/2014-January/034323.html
For reference:
- Public headers should just declare the dump() method but not use
LLVM_DUMP_METHOD or #if !defined(NDEBUG) || defined(LLVM_ENABLE_DUMP)
- The definition of a dump method should look like this:
#if !defined(NDEBUG) || defined(LLVM_ENABLE_DUMP)
LLVM_DUMP_METHOD void MyClass::dump() {
// print stuff to dbgs()...
}
#endif

It's likely if a conditional branch needs to be expanded, the following
unconditional branch will also need expansion. By expanding the
unconditional branch first, the conditional branch can be simply
inverted to jump over the inserted indirect branch block. If the
conditional branch is expanded first, it results in an additional
branch.
This avoids test regressions in future commits.
