306b62b4ae Switch SBWatchpoint::SetEnabled over to using Process::{Enable,Disable}Watchpoint.
We don't have a good story for what happens to watchpoints when you don't
have a process, or if your process exits.  Clearing that up will instruct 
how to fix this for real.

Also added a test to make sure disable->enable works as well.
This resolves llvm.org/pr30789.

5a19c0cc50 Minidump plugin: Fix flaky test
Summary:
One of the tests was flaky, because similarly to
https://reviews.llvm.org/D18697 (rL265391) - if there is a process running
which is with the same PID as in the core file, the minidump
core file debugging will fail, because we get some information from the
running process.
The fix is routing the ProcessInfo requests through the Process class
and overriding it in ProcessMinidump to return correct data.

7b18dd4f77 Minidump plugin: Adding ProcessMinidump, ThreadMinidump and register the plugin in SystemInitializerFull
Summary:
This plugin resembles the already existing Windows-only Minidump plugin.
The WinMinidumpPlugin uses the Windows API for parsing Minidumps
while this plugin is cross-platform because it includes a Minidump
parser (which is already commited)

It is able to produce a backtrace, to read the general puprose regiters,
inspect local variables, show image list, do memory reads, etc.

For now the only arches that this supports are x86_32 and x86_64.
This is because I have only written register contexts for those.
Others will come in next CLs.

I copied the WinMinidump tests and adapted them a little bit for them to
work with the new plugin (and they pass)
I will add more tests, aiming for better code coverage.

There is still functionality to be added, see TODOs in code.

42eb6908e0 Don't set a software stepping breakpoint at 0 on arm or mips.
Summary:
Check whether the setting the breakpoint failed during instruction emulation. If
it did, the next pc is likely in unmapped memory, and the inferior will crash
anyway after the next instruction. Do not return an error in this case, but just
continue stepping.
Reenabled the crash during step test for android/linux.

2e8fe80447 Revert "Fix a race condition between "ephemeral watchpoint disable/enable" and continue in commands."
This reverts commit r284795, as it breaks watchpoint handling on arm (and
presumable all architectures that report watchpoint hits without executing the
tripping instruction).

There seems to be something fundamentally wrong with this patch: it uses
process_sp->AddPreResumeAction to re-enable the watchpoint, but the whole point
of the step-over-watchpoint logic (which AFAIK is the only user of this class) is
to disable the watchpoint *after* we resume to do the single step.

I have no idea how to fix this except by reverting the offending patch.

The lldbutil.run_break_set_by_file_and_line has already checked that the number of 
locations was 1, so don't check it again.  And certainly don't check it again by 
grubbing in break list output.

Also, we know the Thread's IsStopped state is wrong, and have a test for that, so 
don't keep testing it in other files where that isn't the primary thing we're testing.
