Before this change, inlining one "invoke" into an outer "invoke" call
site can lead to the outer landingpad's catch/filter clauses being
copied multiple times into the resulting landingpad.  This happens:

 * when the inlined function contains multiple "resume" instructions,
   because forwardResume() copies the clauses but is called multiple
   times;

 * when the inlined function contains a "resume" and a "call", because
   HandleCallsInBlockInlinedThroughInvoke() copies the clauses but is
   redundant with forwardResume().

Fix this by deduplicating the code.

This problem doesn't lead to any incorrect execution; it's only
untidy.

This change will make fixing PR17872 a little easier.

Employed the following refactorings:
  - Renamed some functions
  - Introduced explaining variables
  - Cleaned up & added comments
  - Used Optional<unsigned> for return value instead of an out parameter
  - Added assertions
  - Constified a few member functions
  
No functionality change.
All regressions pass.

They were out of place since the introduction of arbitrary precision integer
types.

This also synchronizes the documentation to Types.h, so it refers to first class
types and single value types.

for vararg functions.

__builtin_types_compatible_p() isn't a C++ type trait at all, rather a GNU C
special-case, so it's fine to use BoolTy the default return type for binary
type traits.

This brings BTT in line with other arities that already default to BoolTy.

Cleanup only, no change in behaviour.

These helper classes take care of the book-keeping the drives the
GenericScheduler heuristics. It is likely that developers writing
target-specific schedulers that work similarly to GenericScheduler
will want to use these helpers too. The immediate goal is to develop a
GenericPostScheduler that can run in place of the old PostRAScheduler,
but will use the new machine model.

No functionality change intended.

GroupedSectionsPass was a complicated pass. That pass's job was to reorder
atoms by section name, so that the atoms with the same section prefix will be
emitted consecutively to the executable. The pass added layout edges to atoms,
and let the layout pass to actually reorder them.

This patch simplifies the design by making GroupedSectionPass to directly
reorder atoms, rather than adding layout edges. This resembles ELF's
ArrayOrderPass.

This patch improves the performance of LLD; it used to take 7.1 seconds to
link LLD with LLD on my Macbook Pro, but it now takes 6.1 seconds.
