	* config/i386/i386.opt (-mavx512vpopcntdq, -mmavx512bitalg): Move from
	ix86_isa_flags2 to ix86_isa_flags.

	OPTION_MASK_ISA_AVX512BITALG and OPTION_MASK_ISA_AVX512VPOPCNTDQ in

	* config/i386/i386.c (ix86_target_string): Move -mavx512vpopcntdq
	and -mavx512bitalg from isa2_opts to isa_opts.

	and set it in x_ix86_isa_flags rather than x_ix86_isa_flags2.
	Formatting fixes.
	(def_builtin): Treat OPTION_MASK_ISA_AVX512BW or
	OPTION_MASK_ISA_AVX512F ored with another option similarly to
	OPTION_MASK_ISA_AVX512VL.  Even for OPTION_MASK_ISA_AVX512VL don't
	clear it if mask is just OPTION_MASK_ISA_AVX512VL itself.

    • compiler: bring escape analysis mostly in line with gc compiler · bb14e19c 
          
    This CL ports the latest (~Go 1.10) escape analysis code from
    the gc compiler. Changes include:
    
    - In the gc compiler, the variable expression is represented
      with the variable node itself (ONAME). It is the same node
      used in the AST for multiple var expressions for the same
      variable. In our case, the var expressions nodes are distinct
      nodes. We need to propagate the escape state from/to the
      underlying variable in getter and setter. We already do it in
      the setter. Do it in the getter as well.
    
    - At the point of escape analysis, some AST constructs have not
      been lowered to runtime calls, for example, map literal
      construction and some builtin calls. Change the analysis to
      work on the non-lowered AST constructs instead of call
      expressions for them. For this to work, the analysis needs to
      look into Builtin_call_expression. Move its class definition
      from expressions.cc to expressions.h, and add necessary
      accessors. Also fix bugs in other runtime call handlings
      (selectsend, ifaceX2Y2, etc.).
    
    - Handle closures properly. The analysis tracks the function
      reference expression, and the escape state is propagated to
      the underlying heap expression for get_backend to do stack
      allocation for non-escaping closures.
    
    - Fix add_dereference. Before, this was doing expr->deref(),
      which undoes an indirection instead of add one. In the gc
      compiler, it adds a level of indirection, which is modeled as
      an OIND node regardless of the type of the expression. We
      can't do this for non-pointer typed expression, otherwise it
      will result in a type error. Instead, we model it with a
      special flavor of Node, "indirect". The flood phase handles
      this by incrementing its level.
    
    - Slicing of an array was not handled correctly. The gc compiler
      has an implicit (compiler inserted) OADDR node for the array,
      so the analysis is actually performed on the address of the
      array. We don't have this implicit address-of expression in
      the AST. Instead, we model this by adding an implicit child to
      the Node of the Array_index_expression representing slicing of
      an array.
    
    - Array_index_expression may represent indexing or slicing. The
      code distinguishes them by looking at whether the type of the
      expression is a slice. This does not work if the slice element
      is a slice. Instead, check whether its end() is NULL.
    
    - Temporary references was handled only in a limited case, as
      part of address-of expression. This CL handles it in general.
      The analysis uses the Temporary_statement as the point of
      tracking, and forwards Temporary_reference_expression to the
      underlying statement when needed.
    
    - Handle call return value flows, escpecially multiple return
      values. This includes porting part of CL 8202, CL 20102, and
      other fixes.
    
    - Support go:noescape pragma.
    
    - Add special handling for self assignment like
      b.buf = b.buf[m:n]. (CL 3162)
    
    - Remove ESCAPE_SCOPE, which was treated essentially the same as
      ESCAPE_HEAP, and was removed from the gc compiler. (CL 32130)
    
    - Run flood phase until fix point. (CL 30693)
    
    - Unnamed parameters do not escape. (CL 38600)
    
    - Various small bug fixes and improvements.
    
    "make check-go" passes except the one test in math/big, when the
    escape analysis is on. The escape analysis is still not run by
    default.

    • compiler: improve escape analysis diagnostics · fa546f0f 
          
    This CL brings escape analysis diagnostics closer to the gc
    compiler's. This makes porting and debugging escape analysis
    code easier. A few changes:
    
    - In the gc compiler, the variable expression is represented
      with the variable node itself (ONAME), the location of which
      is the location of definition. We add a definition_location
      method to Node, and make use of it when the gc compiler emits
      diagnostics at the definition locations.
    
    - In the gc compiler, methods are named T.M or (*T).M. Add the
      type to the method name when possible.
    
    - Print "moved to heap" messages only for variables.
    
    - Reduce some duplicated diagnostics.
    
    - Print "does not escape" messages in more situations which the
      gc compiler does.
    
    - Remove the special handling for closure numbers. In gofrontend,
      closures are named "$nested#" where # is a global counter
      starting from 0, whereas in the gc compiler they are named
      "outer.func#" where # is a per-function counter starting from
      1. We tried to adjust the closure name to better matching the
      ones in the gc compiler, however, it cannot match exactly
      because of the difference of the counter. Instead, just print
      "outer.$nested#".
