Go 1.15 support (#2011)
* proc: start variable visibility one line after their decl line

In most cases variables shouldn't be visible on their declaration line
because they won't be initialized there.
Function arguments are treated as an exception.

This fix is only applied to programs compiled with Go 1.15 or later as
previous versions of Go did not report the correct declaration line for
variables captured by closures.

Fixes #1134

* proc: silence go vet error

* Makefile: enable PIE tests on windows/Go 1.15

* core: support core files for PIEs on windows

* goversion: add Go 1.15 to supported versions

* proc: fix function call injection for Go 1.15

Go 1.15 changed the call injection protocol so that the runtime will
execute the injected call on a different (new) goroutine.

This commit changes the function call support in delve to:

1. correctly track down the call injection state after the runtime
   switches to a different goroutine.
2. correctly perform the escapeCheck when stack values can come from
   multiple goroutine stacks.

* proc: miscellaneous fixed for call injection under macOS with go 1.15

- create copy of SP in debugCallAXCompleteCall case because the code
  used to assume that regs doesn't change
- fix automatic address calculation for function arguments when an
  argument has a spurious DW_OP_piece at entry

tests: fix flakiness of of TestIssue414 on windows (#2082)
Recent change #2061:

292f5c69f0c769fd32c2e8b1e7153b56e908efd7
proc: step into unexported runtime funcs when already inside runtime

means that TestIssue414 (which tries to step repeatedly until the
program exits) can now steps through way more runtime code than it ever
did before. This causes this test to occasionally fail. Stepping
blindly through runtime code has never been particularly safe as the
runtime can switch to a different goroutine causing Delve to misbehave.

This change restores the previous behavior of TestIssue414 where Step
behaved like Next inside runtime code.

gdbserial: ensure registers are loaded in SetDX/SetSP/SetPC (#2054)
These methods only work if registers have been loaded once after the

terminal/command: Add 'reload' command (#1971)
* terminal/command: Add 'reload' command

These changes add the 'reload' command, which allows us to rebuild the project
and start the debugging session again. Currently, if the project's code is
updated while debugging it, Delve shows the new source code, but it's still
running the old one. With 'reload', the whole binary is rebuilt, and the
process starts again.

proc: step into unexported runtime funcs when already inside runtime (#2061)
Normally we don't step into unexported runtime functions because the
compiler is free to insert them into the code and they are not relevant
to the user, however if we are already stepping through a runtime
function we should let step into work normally and step into other
runtime functions.

service/api: do not try to convert unreadable goroutines (#2070)
When reading truncated core files GoroutinesInfo will sometimes produce
some proc.G structs with only the Unreadable field set. These proc.G
can not be used for anything, but the service layer will still try to
convert them.
Since they are not fully initialized parts of the conversion will fail,
api.ConvertGoroutine should not try to call methods of unreadable
goroutines.

Fixes a bug reported on the mailing list.

terminal: fix nil pointer dereference when printing tracepoints (#2071)
This issue causes a failure of TestTracePid that was observed in CI:

https://travis-ci.com/github/go-delve/delve/jobs/343053383

I'm not sure what causes it in this particular instance but there are
several ways in which a thread stopped at a breakpoint might have a
BreakpointInfo == nil field (see variable withBreakpointInfo in
debugger.Debugger.Command).

proc/*: only load floating point registers when needed (#1981)
Changes implementations of proc.Registers interface and the
op.DwarfRegisters struct so that floating point registers can be loaded
only when they are needed.
Removes the floatingPoint parameter from proc.Thread.Registers.
This accomplishes three things:

1. it simplifies the proc.Thread.Registers interface
2. it makes it impossible to accidentally create a broken set of saved
   registers or of op.DwarfRegisters by accidentally calling
   Registers(false)
3. it improves general performance of Delve by avoiding to load
   floating point registers as much as possible

Floating point registers are loaded under two circumstances:

1. When the Slice method is called with floatingPoint == true
2. When the Copy method is called

Benchmark before:

BenchmarkConditionalBreakpoints-4   	       1	4327350142 ns/op

Benchmark after:

BenchmarkConditionalBreakpoints-4   	       1	3852642917 ns/op

cmd/dlv: Fix trace output (#2038)
* cmd/dlv,debugger: Improve dlv trace and trace command output

This patch improves the `dlv trace` subcommand output by reducing the
noise that is generated and providing clearer more concise information.

Also adds new tests closing a gap in our testing (we previously never
really tested this subcommand).

This patch also fixes the `dlv trace` REPL command to behave like the
subcommand in certain situations. If the tracepoint is for a function,
we now show function arguements and return values properly.

Also makes the overall output of the trace subcommand clearer.
