top-down scheduling and top-down scheduling is going away.

fbc0dec7b4 Reset the system compiler each time we start a new flavour. Otherwise
the last compiler built for the previous flavour is used for the next,
for example the Debug clang compiler was being used for the initial build
of the Release LLVM.  Flavors should be independent of each other.  This
especially matters if the compiler built for the previous flavour doesn't
actually work!

1dda3d511e Haven't yet found a nice way to handle TargetData verification in the
AsmParser. This patch adds validation for target data layout strings upon
construction of TargetData objects. An attempt to construct a TargetData object
from a malformed string will trigger an assertion.

c66330504c Refactor code from inlining and globalopt that checks whether a function definition is unused, and enhance it so it can tell that functions which are only used by a blockaddress are in fact dead. This probably doesn't happen much on most code, but the Linux kernel's _THIS_IP_ can trigger this issue with blockaddress. (GlobalDCE can also handle the given tescase, but we only run that at -O3.) Found while looking at PR11180.

815af82b74 Improve code generation for vselect on SSE2:
When checking the availability of instructions using the TLI, a 'promoted'
instruction IS available. It means that the value is bitcasted to another type
for which there is an operation. The correct check for the availablity of an
instruction is to check if it should be expanded.

cdd8e46bec Use literal pool loads instead of MOVW/MOVT for materializing global addresses when optimizing for size.
On spec/gcc, this caused a codesize improvement of ~1.9% for ARM mode and ~4.9% for Thumb(2) mode. This is
codesize including literal pools.

The pools themselves doubled in size for ARM mode and quintupled for Thumb mode, leaving suggestion that there
is still perhaps redundancy in LLVM's use of constant pools that could be decreased by sharing entries.

Fixes PR11087.

d3d1cad535 Implement Paste
Add a paste operator '#' to take two identifier-like strings and joint
them.  Internally paste gets represented as a !strconcat() with any
necessary casts to string added.

This will be used to implement basic for loop functionality as in:

for i = [0, 1, 2, 3, 4, 5, 6, 7] {
  def R#i : Register<...>
}

f3744a0cf9 Make ID Parsing More Flexible
Add a mode control to value and ID parsers.  The two modes are:

- Parse a value.  Expect the parsed ID to map to an existing object.

- Parse a name.  Expect the parsed ID to not map to any existing object.

The first is used when parsing an identifier to be looked up, for
example a record field or template argument.  The second is used for
parsing declarations.  Paste functionality implies that declarations
can contain arbitrary expressions so we need to be able to call into
the general value parser to parse declarations with paste operators.
So we need a way to parse a value-like thing without expecting that
the result will map to some existing object.  This parse mode provides
that.
