Add a scheduling model for AMD 16H Jaguar (btver2).

This is a first pass at a scheduling model for Jaguar.
It's structured largely on the existing SandyBridge and SLM sched models.

Using this model, in addition to turning on the PostRA scheduler, results in 
some perf wins on internal and 3rd party benchmarks. There's not much difference 
in LLVM's test-suite benchmarking subset of tests.

Handle common linkage correctly in the gold plugin.

This is the plugin version of pr20882.

This handles the case of every common symbol being in the IR. We will need some
support from gold to handle the case where some symbols are in ELF and some in
the IR.

Remove DwarfDebug::PrevSection, PrevCU is sufficient for handling address range holes.

PrevSection/PrevCU are used to detect holes in the address range of a CU
to ensure the DW_AT_ranges does not include those holes. When we see a
function with no debug info, though it may be in the same range as the
prior and subsequent functions, there should be a gap in the CU's
ranges. By setting PrevCU to null in that case, the range would not be
extended to cover the gap.

Sink PrevCU updating into DwarfUnit::addRange to ensure consistency

So that the two operations in DwarfDebug couldn't get separated (because
I accidentally separated them in some work in progress), put them
together. While we're here, move DwarfUnit::addRange to
DwarfCompileUnit, since it's not relevant to type units.

Attempt to fix PR20884

This fixes the generation of broken LLVMExports.cmake file by
the Autoconf/Makefile build system when --enable-shared is passed to
configure.

When --enable_shared is passed the Makefile.rules does not set the
LLVMConfigLibs variable which cmake/modules/Makefile previously relied
on. Now it runs the llvm-config command itself to get the library names.

This still isn't perfect because the generated LLVM targets refer to the
static libraries and not the shared library but that is much larger
problem to fix.
