Previously we put a WatchpointSentry object within StopInfo.cpp to disable-and-then-enable the watchpoint itself
while we are performing the actions associated with the triggered watchpoint, which can cause the user-initiated
watchpoint disabling action to be negated.
Add a test case to verify that a watchpoint can be disabled during the callbacks.

by CodeGen.
In the long-term, much of the codegen logic will be shared between the GNU-style
and MS-style inline assembly, but for now I'm replicating this logic to avoid
regressions with the GNU-style.

lookup table as needing to be built.
This is required for LLDB, which provides the
contents of many DeclContexts through a custom
ExternalASTSource.

"castAs<...>->doSomething()". The analyzer was flagging these
as potential null dereferences, which is technically true. The
invariants appear to be that these casts should never fail, so
let's use castAs<> instead and avoid a runtime check.

statement starts with an identifier for which name lookup will fail either way,
look at later tokens to disambiguate in order to improve error recovery.

Currently, TableGen just guesses instruction properties when it can't
infer them form patterns.
This adds a guessInstructionProperties flag to the instruction set
definition that will be used to disable guessing. The flag is intended
as a migration aid. It will be removed again when no more targets need
their properties guessed.

A CXXDefaultArgExpr wraps an Expr owned by a ParmVarDecl belonging to the
called function. In general, ExprEngine and Environment ought to treat this
like a ParenExpr or other transparent wrapper expression, with the inside
expression evaluated first.
However, if we call the same function twice, we'd produce a CFG that contains
the same wrapped expression twice, and we're not set up to handle that. I've
added a FIXME to the CFG builder to come back to that, but meanwhile we can
at least handle expressions that don't need to be explicitly evaluated:
literals. This probably handles many common uses of default parameters:
true/false, null, etc.

Deallocate: drain blocks to central cache if cached too much (instead of never drain).
Allocate: batch allocate fixed amount of blocks (instead of all blocks).
This significantly reduces memory consumption of large heavy-multithreaded programs.

(kudos to Anna Zaks for a good example).
This simplifies the code much and lets us not implement internal parts of libdispatch.
All ASan tests from t32 and t64 should pass with the dylib runtime now.

The logic for recomputing latency based on a ScheduleDAG edge was
shady. This bypasses the problem by requiring the client to provide
operand indices. This ensures consistent use of the machine model's
API.

Added a new "interpreter" properties to encapsulate any properties for the command interpreter. Right now this contains only "expand-regex-aliases", so you can now enable (disabled by default) the echoing of the command that a regular expression alias expands to:
(lldb) b main
Breakpoint created: 1: name = 'main', locations = 1
Note that the expanded regular expression command wasn't shown by default. You can enable it if you want to:
(lldb) settings set interpreter.expand-regex-aliases true
(lldb) b main
breakpoint set --name 'main'
Breakpoint created: 1: name = 'main', locations = 1
Also enabled auto completion for enumeration option values (OptionValueEnumeration) and for boolean option values (OptionValueBoolean).
Fixed auto completion for settings names when nothing has been type (it should show all settings).
