In an effort to make -flimit-debug-info more consistent I over-shot the
mark & made types used via typedefs never produce definitions in the
debug info (even if the type was used in a way that would require a
definition).

The fix for this is to do exactly what I was hoping to do at some point
- plumb the declaration/definition choice through the various layers of
"CreateType" in CGDebugInfo. In this way we can produce declarations
whenever they are sufficient & definitions otherwise - including when
qualifiers are used, for example (discovered in PR14467). This may not
be complete (there may be other types/situations where we need to
propagate the "declaration/definition" choice) but it lays the basic
foundation which we can enhance in future iterations.

This could actually be implemented with the LLVM IR va_arg instruction,
but it doesn't seem to offer any advantages over accessing the va_list
pointer directly.

Using the va_list pointer directly makes it possible to perform type
coercion directly from the argument array, and the va_list updates are
exposed to the optimizers.

Type coercion for argument passing is equivalent to storing the source
type and loading the destination type from the same pointer. On
big-endian targets, this means that the high bits of integers are
preserved.

This patch fixes the CoerceIntOrPtrToIntOrPtr() function on big-endian
targets by inserting the required shift instructions to preserve the
high bits instead of the low bits.

This is used by SparcABIInfo when passing small structs in the high bits
of registers.

The 'inreg' attribute can also be applied to function return values in
LLVM IR. The SPARC v9 backend is using the flag when returning structs
containing 32-bit floats.

In ELF (as in MachO), not all relocations point to symbols. Represent this
properly by using a symbol_iterator instead of a SymbolRef. Update llvm-readobj
ELF's dumper to handle relocatios without symbols.

handle temporaries which have been lifetime-extended to static storage duration
within constant expressions. This correctly handles nested lifetime extension
(through reference members of aggregates in aggregate initializers) but
non-constant-expression emission hasn't yet been updated to do the same.

Two things:
1) fixing a bug where memory read was not clearing the m_force flag after it was passed, so that subsequent memory reads would not need to be forced even if over boundary
2) adding a setting target.max-memory-read-size that you can set instead of the hardcoded 1024 bytes limit we had before

Performance timers captured in each transform for all files they process are now collected and arranged per source file in preparation for writing to disk.

If you want to define a formatter for "array of Foo of any size", ordinarily you would say

-x "Foo \[[0-9]+\]"

this checkin allows you to instead say "Foo[]" (or "Foo []") and LLDB will automatically create the regular expression and add the -x flag on your behalf
