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).

the temporary register that was used to load the immediate. Currently, it always
returns register $at, but this will change if, in the future, we decide to use
another register.
No changes in functionality.

When reporting an error for a defm, we would previously only report the
location of the outer defm, which is not always where the error is.
Now we also print the location of the expanded multiclass defs:
lib/Target/X86/X86InstrSSE.td:2902:12: error: foo
defm ADD : basic_sse12_fp_binop_s<0x58, "add", fadd, SSE_ALU_ITINS_S>,
^
lib/Target/X86/X86InstrSSE.td:2801:11: note: instantiated from multiclass
defm PD : sse12_fp_packed<opc, !strconcat(OpcodeStr, "pd"), OpNode, VR128,
^
lib/Target/X86/X86InstrSSE.td:194:5: note: instantiated from multiclass
def rm : PI<opc, MRMSrcMem, (outs RC:$dst), (ins RC:$src1, x86memop:$src2),

name. This should reduce the amount of warning false positives about bad HTML
in comments when the comment author intended to put a reference to a template.
This change will also enable us parse the comment as intended in these cases.
Fixes part 1 of PR13374.
