compiler: bring escape analysis mostly in line with gc compiler
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
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#".

[-fcompare-debug] retain insn locations when turning dbr seq into return
A number of -fcompare-debug errors on sparc arise as we split a dbr

If we just take the location from the PREV_INSN, it might be a debug
insn without INSN_LOCATION, or an insn with an unrelated location.

its own INSN_LOCATION, so use that instead, even though some may have

Better would be to simply use the fact that we will always be overwriting

We already specify as such in the arm-cpus.in entries for
