This commit adds the change on asm_ppc64.s and tls_ppc64.s files for AIX
operating system.
R2 does not need to be set for aix/ppc64 since it should remain valid
througout Go execution, except after a call to a C function.
Moreover, g must always be saved on the tls as syscalls are made with
C functions.
Some modifications on asm_ppc64.s are due to AIX stack layout.
It also removes a useless part in asmcgocall which was done twice.

crypto/tls is meant to work over network connections with buffering, not
synchronous connections, as explained in #24198. Tests based on net.Pipe
are unrealistic as reads and writes are matched one to one. Such tests
worked just thanks to the implementation details of the tls.Conn
internal buffering, and would break if for example the flush of the
first flight of the server was not entirely assimilated by the client
rawInput buffer before the client attempted to reply to the ServerHello.
Note that this might run into the Darwin network issues at #25696.
Fixed a few test races that were either hidden or synchronized by the
use of the in-memory net.Pipe.
Also, this gets us slightly more realistic benchmarks, reflecting some
syscall cost of Read and Write operations.

Recent change golang.org/cl/142737 drops the only call site for the
sortKeys function. If it's not in use, it should probably not be there in
the code, lurking and preparing to bite us when someone calls that instead
of the new key sorter in fmtsort, resulting in strange inconsistencies.
Since the function isn't called, this should have no impact.

For easier testing, change the way maps are printed so they
appear in a consistent order between runs. Do this by printing
them in key-sorted order.
To do this, we add a package at the root, internal/fmtsort,
that implements a general mechanism for sorting map keys
regardless of their type. This is a little messy and probably
slow, but formatted printing of maps has never been fast and
is already always reflection-driven.
The rules are:
The ordering rules are more general than with Go's < operator:
- when applicable, nil compares low
- ints, floats, and strings order by <
- NaN compares less than non-NaN floats
- bool compares false before true
- complex compares real, then imag
- pointers compare by machine address
- channel values compare by machine address
- structs compare each field in turn
- arrays compare each element in turn.
- interface values compare first by reflect.Type describing the concrete type
and then by concrete value as described in the previous rules.
The new package is internal because we really do not want
everyone using this to sort things. It is slow, not general, and
only suitable for the subset of types that can be map keys.
Also use the package in text/template, which already had a
weaker version of this mechanism.
This change requires adding a dependency on sort to the fmt
package, but that isn't disruptive to the dependency tree.

The spec currently provides a syntactic rule for receiver base types,

referring to pointer types as receiver types.
This strict interpretation breaks an assumed rule for aliases, which
is that a type literal can always be replaced by an alias denoting
that literal.
Furthermore, cmd/compile always accepted this new formulation of the
receiver type rules and so this change will simply validate what has

The reason was that decodeState.object would return a nil error on
encountering the invalid map key string, while saving the key type error

abruptly end parsing the nested object, leaving the decoder in an
unexpected state.
To fix this, simply avoid storing the map element and continue decoding

In golang.org/cl/75310, the compiler's typechecker was changed so that
map key types were validated at a later stage, to make sure that all the
necessary type information was present.
This still worked for map type declarations, but caused a regression for
top-level map variable declarations. These now caused a fatal panic
instead of a typechecking error.
The cause was that checkMapKeys was run too early, before all
typechecking was done. In particular, top-level map variable
declarations are typechecked as external declarations, much later than
where checkMapKeys was run.
Add a test case for both exported and unexported top-level map
declarations, and add a second call to checkMapKeys at the actual end of
typechecking. Simply moving the one call isn't a good solution either;
the comments expand on that.
