Simplify range location creation in C++ parser.
Many places in the parser follow the same pattern of capturing the location

lexer to make_location and grabbing the token location there.

runtime: expose the g variable
Currently, getg is implemented in C, which loads the thread-local
g variable. The g variable is declared static in C.
This CL exposes the g variable, so it can be accessed from the Go
side. This allows the Go compiler to inline getg calls to direct
access of g.
Currently, the actual inlining is only implemented in the gollvm
compiler. The g variable is thread-local and the compiler backend
may choose to cache the TLS address in a register or on stack. If
a thread switch happens the cache may become invalid. I don't
know how to disable the TLS address cache in gccgo, therefore
the inlining of getg is not implemented. In the future gccgo may
gain this if we know how to do it safely.

compiler: ensure evaluation order in type hash/eq functions
The type hash and equality functions are generated after the
order_evaluations pass. They may contain shortcut operators and
Set_and_use_temporary_expressions (e.g. from lowering a
Binary_exprssion) that need to be ordered. Run order_evaluations
and remove_shortcuts on these functions. (The hash functions
may be fine, but to be on the safe side we run on them anyway.
We do need to run on the equality functions.)
A Set_and_use_temporary_expression is effectively an assignment,
so it needs to be ordered. Otherwise if we insert a temporary
statement before it, we may get wrong evaluation order.
A test case is CL 185818.

[Ada] New Repinfo.Input unit to read back JSON representation info.
For some time the Repinfo unit has been able to output the
representation information in the JSON data interchange format in
addition to the usual text and binary formats.
The new Repinfo.Input unit makes it possible to read back this
information under this format and make it available to clients, the main
one being ASIS.
The big advantage of using this approach over manipulating a binary blob
is that the writer and the reader of the JSON representation need not be
binary compatible, i.e. in practice need not be the same version of the
compiler or ASIS for the same target.
The patch also adds a -gnatd_j switch to read back the information in
the compiler itself, which makes it easy to keep the writer and the
reader in sync using only one tool, namely the compiler. The typical
usage is:
gcc -c p.ads -gnatR4js

[Ada] Elaboration order v4.0 and infinite loops
This patch introduces binder switch -d_S which prompts the various
phases of the elaboration order mechanism to output a short message
concerning their commencement and completion. The output is useful when
trying to determine whether a phase is stuck in an infinite loop.

[Ada] Avoid spurious warning on wrong order of operator call arguments
GNAT issues a warning under -gnatwa when actuals for a call are named
like the formals, but in a different order. This is inappropriate for
calls to operators in infix form, when e.g. Right <= Left is in general
the intended order. Special case calls to operators to avoid that
spurious warning.
