compiler: make use of specialized fast map routines
In the runtime there are specialized fast map routines for
certain kep types. This CL lets the compiler make use of these
functions, instead of always using the generic ones.
As we now generate multiple versions of map delete calls, to make
things easier we delay the expansion of the built-in delete
function to flatten phase.

compiler, runtime, reflect: generate unique type descriptors
Currently, the compiler already generates common symbols for type
descriptors, so the type descriptors are unique. However, when a
type is created through reflection, it is not deduplicated with
compiler-generated types. As a consequence, we cannot assume type
descriptors are unique, and cannot use pointer equality to
compare them. Also, when constructing a reflect.Type, it has to
go through a canonicalization map, which introduces overhead to
reflect.TypeOf, and lock contentions in concurrent programs.
In order for the reflect package to deduplicate types with
compiler-created types, we register all the compiler-created type
descriptors at startup time. The reflect package, when it needs
to create a type, looks up the registry of compiler-created types
before creates a new one. There is no lock contention since the
registry is read-only after initialization.
This lets us get rid of the canonicalization map, and also makes
it possible to compare type descriptors with pointer equality.

libgo: delay applying profile stack-frame skip until fixup
When the runtime collects a stack trace to associate it with some
profiling event (mem alloc, mutex, etc) there is a skip count passed
to runtime.Callers (or equivalent) to skip some known count of frames
in order to get to the "interesting" frame corresponding to the
profile event. Now that the profiling mechanism uses lazy fixup (when
removing compiler artifacts like thunks, morestack calls etc), we also
need to move the frame skipping logic after the fixup, so as to insure
that the skip count isn't thrown off by these artifacts.

This requires tracking all references to unexported variables, so that
we can make them global symbols in the object file, and can export
them so that other compilations can see the right definition for their

This introduces a syntax for referencing names defined in other
packages: a <pNN> prefix, where NN is the package index. This will
need to be added to gccgoimporter, but I didn't do it yet since it

Fix PR64242 - Longjmp expansion incorrect
Improve the fix for PR64242. Various optimizations can change a memory
reference into a frame access. Given there are multiple virtual frame pointers
which may be replaced by multiple hard frame pointers, there are no checks for
writes to the various frame pointers. So updates to a frame pointer tends to
generate incorrect code. Improve the previous fix to also add clobbers of
several frame pointers and add a scheduling barrier. This should work in most
cases until GCC supports a generic "don't optimize across this instruction"
feature.
Bootstrap OK. Testcase passes on AArch64 and x86-64. Inspected x86, Arm,
Thumb-1 and Thumb-2 assembler which looks correct.

aarch64: emit .variant_pcs for aarch64_vector_pcs symbol references
A dynamic linker with lazy binding support may need to handle vector PCS
function symbols specially, so an ELF symbol table marking was
introduced for such symbols.
Function symbol references and definitions that follow the vector PCS
are marked in the generated assembly with .variant_pcs and then the
STO_AARCH64_VARIANT_PCS st_other flag is set on the symbol in the object
file. The marking is propagated to the dynamic symbol table by the
static linker so a dynamic linker can handle such symbols specially.
For this to work, the assembler, the static linker and the dynamic
linker has to be updated on a system. Old assembler does not support
the new .variant_pcs directive, so a toolchain with old binutils won't
be able to compile code that references vector PCS symbols.

Enforce allocator::value_type consistency for containers in C++2a
In previous standards it is undefined for a container and its allocator
to have a different value_type. Libstdc++ has traditionally allowed it
as an extension, automatically rebinding the allocator to the
container's value_type. Since GCC 8.1 that extension has been disabled
for C++11 and later when __STRICT_ANSI__ is defined (i.e. for
-std=c++11, -std=c++14, -std=c++17 and -std=c++2a).
Since the acceptance of P1463R1 into the C++2a draft an incorrect
allocator::value_type now requires a diagnostic. This patch implements
that by enabling the static_assert for -std=gnu++2a as well.

[AArch64] Emit TARGET_DOTPROD-specific sequence for <us>sadv16qi
Wilco pointed out that when the Dot Product instructions are available we can use them
to generate an even more efficient expansion for the [us]sadv16qi optab.
Instead of the current:
uabdl2 v0.8h, v1.16b, v2.16b
uabal v0.8h, v1.8b, v2.8b
uadalp v3.4s, v0.8h
we can generate:
(1) mov v4.16b, 1
(2) uabd v0.16b, v1.16b, v2.16b
(3) udot v3.4s, v0.16b, v4.16b
Instruction (1) can be CSEd across multiple such expansions and even hoisted outside of loops,
so when this sequence appears frequently back-to-back (like in x264_r) we essentially only have 2 instructions
per sum. Also, the UDOT instruction does the byte-to-word accumulation in one step, which allows us to use
the much simpler UABD instruction before it.
This makes it a shorter and lower-latency sequence overall for targets that support it.
