[Target] remove TargetRecip class; 2nd try
This is a retry of r284495 which was reverted at r284513 due to use-after-scope bugs
caused by faulty usage of StringRef.
This version also renames a pair of functions:
getRecipEstimateDivEnabled()
getRecipEstimateSqrtEnabled()
as suggested by Eric Christopher.
original commit msg:
[Target] remove TargetRecip class; move reciprocal estimate isel functionality to TargetLowering
This is a follow-up to https://reviews.llvm.org/D24816 - where we changed reciprocal estimates to be function attributes
rather than TargetOptions.
This patch is intended to be a structural, but not functional change. By moving all of the
TargetRecip functionality into TargetLowering, we can remove all of the reciprocal estimate
state, shield the callers from the string format implementation, and simplify/localize the
logic needed for a target to enable this.
If a function has a "reciprocal-estimates" attribute, those settings may override the target's
default reciprocal preferences for whatever operation and data type we're trying to optimize.
If there's no attribute string or specific setting for the op/type pair, just use the target
default settings.
As noted earlier, a better solution would be to move the reciprocal estimate settings to IR
instructions and SDNodes rather than function attributes, but that's a multi-step job that
requires infrastructure improvements. I intend to work on that, but it's not clear how long
it will take to get all the pieces in place.

Minidump plugin: redesign the x86_64 register context
Summary:
I misunderstood the format of the register context layout.
I thought it was a dynamically changing structure, and that it's size
depended on context_flags.
It turned out that it always has the same fixed layout and size,
and the context_flags says which fields of the
struct have valid values.
This required a minor redesign of the register context class.
The layout inconsistency, however, was not a "problem" before (e.g. the plugin was working)
because there also was a bug with checking context_flags - the code was
parsing the entire struct regardless of context_flags.
This bug is also fixed in this commit.

void foo(){

Next set of additional error checks for invalid Mach-O files for the
load commands that use the MachO::thread_command type
but are not used in llvm libObject code but used in llvm tool code.
This includes the LC_UNIXTHREAD and LC_THREAD
load commands.
A quick note about the philosophy of the error checking in
libObject for Mach-O files, the idea behind the checking is
that we never will return a Mach-O file out of libObject that
contains unknown things in the load commands.
To do this the 32-bit ARM and PPC general tread states
needed to be defined as two test case binaries contained
them. If other thread states for other CPUs need to be
added we will do that as needed.
Going forward the LC_MAIN load command is used to
set the entry point in Mach-O executables these days
instead of an LC_UNIXTHREAD as was done in the past.
So today only in core files are LC_THREAD load commands
and thread states usually found.
Other thread states have not yet been defined in
include/Support/MachO.h at this time. But that can be
added as needed with their corresponding checking also
added.

Add lldb register definitions for w0-w28, s0-s31, and d0-d31 to
RegisterInfos_arm64.h. These register definitions include the
offset into the register context, which will vary depending on the
endianness of the arm64 target system (e.g. s8 is at offset 0 in
v8 on little-endian, it is at offset 12 on big-endian) and I've
only added the little-endian definitions to the table. If we want
to add a big-endian arm64 target, we'll need a separate table which
uses the big-endian offsets for these registers. I changed the
name of the register table from g_register_infos_arm64 to
g_register_infos_arm64_le to make it explicit that this is the
little-endian version of that table, and updated users of the table
to use the new name.
I added support for the "w", "s", and "d" registers to
RegisterContextDarwin_arm64 but it was more an example than anything
useful -- this plugin is only used when working with core files and
darwin core files do not (today) include the floating point register
context, so it only added the support for the "w" pseudo registers.
When we're connected to a real arm64 device, we use the ProcessGDBRemote
code.

[PGO] Fix bogus warning for merging empty llvm profile file
Profile runtime can generate an empty raw profile (when there is no function in
the shared library). This empty profile is treated as a text format profile. A
test format profile without the flag of "#IR" is thought to be a clang
generated profile. So in llvm profile merging, we will get a bogus warning of
"Merge IR generated profile with Clang generated profile."
The fix here is to skip the empty profile (when the buffer size is 0) for
profile merge.

Remove the JIT EH/small code model tests for now.
These tests rely on two sections being allocated with a limited displacement
from one to the other to work. We've never guaranteed this, and consequently
these tests usually fail. That led to them being XFAILed, but now they XPASS
whenever the sections do happen to be allocated nearby in memory. So I'm
removing these for now to get rid of the noise. We can re-instate them if/when
we take the time to implement a displacement-respecting allocator.
