Reverting "CMake: Don't include tools, unittets, or examples as

It breaks the configuration phase when cmake is invoked without
parameters, it is too complex for the purpose and introduces an
incovenience for the user (as both LLVM_BUILD_X and LLVM_INCLUDE_X

LoadPRE was not properly checking that the load it was PRE'ing post-dominated the block it was being hoisted to.
Splitting critical edges at the merge point only addressed part of the issue; it is also possible for non-post-domination
to occur when the path from the load to the merge has branches in it.  Unfortunately, full anticipation analysis is
time-consuming, so for now approximate it.  This is strictly more conservative than real anticipation, so we will miss
some cases that real PRE would allow, but we also no longer insert loads into paths where they didn't exist before. :-)

This is a very slight net positive on SPEC for me (0.5% on average).  Most of the benchmarks are largely unaffected, but
when it pays off it pays off decently: 181.mcf improves by 4.5% on my machine.

Fix Getting Started docs.
configure expects LLVM Test Suite to be in projects/test-suite.
Made the "getting started" and "testing infrastructure" docs internally consistent.
Avoid confusion between llvm-test and llvm/test.

Correctly handle weak undefined symbols. Before we would get a invalid binding

Fix r114632. Return if the only terminator is an unconditional branch after the redundant ones are deleted.

Fix opcode value for the 'trap' instruction, keeping the type suffix on the
constant. Hopefully the non-Darwin bots will like it...

explicit 'unsigned long' on constant value. Hopefully make bots happier.

Revert 114634 for now since buildbot claim it broke Clang self-hosting. I doubt it but it's possible it's exposing another bug somewhere.

Clean up the 'trap' instruction printing a bit. Non-Darwin assemblers don't
(yet) recognize the 'trap' mnemonic, so we use .short/.long to emit the
opcode directly. On Darwin, however, we do want the mnemonic for more
readable assembly code and better disassembly.

Adjust the .td file to use the 'trap' mnemonic and handle using the binutils
workaround in the assembly printer. Also tweak the formatting of the opcode
values to make them consistent between the MC printer and the old printer.

Correctly compute the offset of the symbol. Forgot these bits from the
last commit.

Represent relocations against local symbols as relocations against the section
they are in. Both ways should be equivalent, but gas produces relocations
against the section.

Fix llvm-extract so that it changes the linkage of all GlobalValues to
"external" even when doing lazy bitcode loading.  This was broken because
a function that is not materialized fails the !isDeclaration() test.
