used in the default function argument as "used". Instead, when we
actually use the default argument, make another pass over the
expression to mark any used declarations as "used" at that point. This
addresses two kinds of related problems:

  1) We were marking some declarations "used" that shouldn't be,
  because we were marking them too eagerly.
  2) We were failing to mark some declarations as "used" when we
  should, if the first time it was instantiated happened to be an
  unevaluated context, we wouldn't mark them again at a later point.

I've also added a potentially-handy visitor class template
EvaluatedExprVisitor, which only visits the potentially-evaluated
subexpressions of an expression. I bet this would have been useful for
noexcept...

Fixes PR5810 and PR8127.

preambles end up leaving the precompiled preambles around. This is by
design, since we do minimal cleanup during crash recovery. However,
it's unfortunate for testing, so introduce a hook that allows these
two tests to put the precompiled preamble somewhere where we can
delete them after testing.

just abort creation of the precompiled preamble rather than doing
silly things. This is the second part of the fix for the weird
preamble-related failures on Windows. Big thanks to Francois Pichet
for the great detective work!

This fixes rdar://8408129 - pushfd and popfd get invalid instruction mnemonic errors

llvm-svn: 113689

the end of the line on a parser error, allowing skipping to happen
for syntactic errors but not for semantic errors.  Before we would
miss emitting a diagnostic about the second line, because we skipped
it due to the semantic error on the first line:

  foo %eax
  bar %al

This fixes rdar://8414033 - llvm-mc ignores lines after an invalid instruction mnemonic errors

This can result in increased opportunities for store narrowing in code generation.  Update a number of
tests for this change.  This fixes <rdar://problem/8285027>.

Additionally, because this inverts the order of ors and ands, some patterns for optimizing or-of-and-of-or
no longer fire in instances where they did originally.  Add a simple transform which recaptures most of these
opportunities: if we have an or-of-constant-or and have failed to fold away the inner or, commute the order 
of the two ors, to give the non-constant or a chance for simplification instead.

They will now be represented as:
eSymbolTypeFunction: eSymbolTypeCode with IsDebug() == true
  eSymbolTypeGlobal: eSymbolTypeData with IsDebug() == true and IsExternal() == true
  eSymbolTypeStatic: eSymbolTypeData with IsDebug() == true and IsExternal() == false

This simplifies the logic when dealing with symbols and allows for symbols
to be coalesced into a single symbol most of the time.

Enabled the minimal symbol table for mach-o again after working out all the
kinks. We now get nice concise symbol tables and debugging with DWARF in the
.o files with a debug map in the binary works well again. There were issues
where the SymbolFileDWARFDebugMap symbol file parser was using symbol IDs and
symbol indexes interchangeably. Now that all those issues are resolved 
debugging is working nicely.

to specify a one-liner (either scripting or lldb command) inline.

Refactored CommandObjectBreakpointCommandAdd::Execute() a little bit and added
some comments.

Sn now, we use:

breakpoint command add -p 1 -o "conditional_break.stop_if_called_from_a()"

to specify a Python one-liner as the callback for breakpoint #1.
