Change ELFCodeEmitter logic to emit the constant pool and jump tables to
...
their appropriate sections before the code itself. They need to be emitted
before the function because on some targets (x86 but not x86_64) the later
may reference a JT or CP entry address

global declared symbols are initialized with references from other global
symbols.

sections).

llvm_unreachable->llvm_unreachable(0), LLVM_UNREACHABLE->llvm_unreachable.
...
This adds location info for all llvm_unreachable calls (which is a macro now) in
!NDEBUG builds.
In NDEBUG builds location info and the message is off (it only prints
"UREACHABLE executed").

assert(0) -> LLVM_UNREACHABLE.
...
Make llvm_unreachable take an optional string, thus moving the cerr<< out of
line.
LLVM_UNREACHABLE is now a simple wrapper that makes the message go away for
NDEBUG builds.
