aarzilli 5155ef047f proc,dwarf/line: support is_stmt and prologue_end flags
Go1.11 uses the is_stmt flag of .debug_line to communicate which
assembly instructions are good places for breakpoints, we should
respect this flag.

These changes were introduced by:
* https://go-review.googlesource.com/c/go/+/102435/

Additionally when setting next breakpoints ignore all PC addresses that
belong to the same line as the one currently under at the cursor. This
matches the behavior of gdb and avoids stopping multiple times at the
heading line of a for statement with go1.11.

Change: https://go-review.googlesource.com/c/go/+/110416 adds the
prologue_end flag to the .debug_line section to communicate the end of
the stack-split prologue. We should use it instead of pattern matching
the disassembly when available.

Fixes #550

dlv debug

Compile and begin debugging main package in current directory, or the package specified.

Synopsis

Compiles your program with optimizations disabled, starts and attaches to it.

By default, with no arguments, Delve will compile the 'main' package in the current directory, and begin to debug it. Alternatively you can specify a package name and Delve will compile that package instead, and begin a new debug session.

dlv debug [package]

Options

      --output string   Output path for the binary. (default "debug")

Options inherited from parent commands

      --accept-multiclient   Allows a headless server to accept multiple client connections. Note that the server API is not reentrant and clients will have to coordinate.
      --api-version int      Selects API version when headless. (default 1)
      --backend string       Backend selection:
	default		Uses lldb on macOS, native everywhere else.
	native		Native backend.
	lldb		Uses lldb-server or debugserver.
	rr		Uses mozilla rr (https://github.com/mozilla/rr).
 (default "default")
      --build-flags string   Build flags, to be passed to the compiler.
      --headless             Run debug server only, in headless mode.
      --init string          Init file, executed by the terminal client.
  -l, --listen string        Debugging server listen address. (default "localhost:0")
      --log                  Enable debugging server logging.
      --log-output string    Comma separated list of components that should produce debug output, possible values:
	debugger	Log debugger commands
	gdbwire		Log connection to gdbserial backend
	lldbout		Copy output from debugserver/lldb to standard output
	debuglineerr	Log recoverable errors reading .debug_line
Defaults to "debugger" when logging is enabled with --log.
      --wd string            Working directory for running the program. (default ".")
