This implements `DoLoadImage` and `UnloadImage` in the Windows platform
plugin modelled after the POSIX platform plugin.  This was previously
unimplemented and resulted in a difficult to decipher error without any
logging.

This implementation is intended to support enables the use of LLDB's
Swift REPL on Windows.

Paths which are added to the library search path are persistent and
applied to all subsequent loads.  This can be adjusted in the future by
storing all the cookies and restoring the path prior to returning from
the helper.  However, the dynamic path count makes this a bit more
challenging.

Building xray with recent clang on a 64-bit system results in a number
of -Wformat warnings:

Avoid the use of deprecated (opaque pointer incompatible) APIs
in C API tests, in preparation for header deprecation. Add a
LLVMGetGEPSourceElementType() to cover a bit of functionality
that is necessary for the echo test.

This change is split out from https://reviews.llvm.org/D114936.

As suggested on D115098, this tests the positioning of
HotColdSplitting, IROutliner and MergeFunctions in the optimization
pipeline.

MergeFunctions (as well as HotColdSplitting an IROutliner) are
incorrectly scheduled under the new pass manager. The code makes
it look like they run towards the end of the module optimization
pipeline (as they should), while in reality the run at the start.
This is because the OptimizePM populated around them is only
scheduled later.

I'm fixing this by moving these three passes until after OptimizePM
to avoid splitting the function pass pipeline. It doesn't seem
important to me that some of the function passes run after these
late module passes.

729bf9b2 should have fixed these

This reverts commits
* ee691970 (D113741),
* 79d31329 (D114705)

due to lldb and dexter test failures.

Code using indirect calls is broken without this, and there isn't
really much value in supporting the old attempt to vary the argument
placement based on uses. This resulted in more argument shuffling code
anyway.

Also have the option stop implying all inputs need to be passed. This
will no rely on the amdgpu-no-* attributes to avoid passing
unnecessary values.

Previously we would require adding an attribute to kernels to enable
the inputs passed in the kernarg segment, accessed by
llvm.amdgcn.implicitarg.ptr. This violates the principle of being
correct by default. Some OpenMP testcases were broken recently since
it wasn't correctly setting this attribute, and no known frontends are
setting this to anything other than the maximum.

Most of the test changes are from load widening of argument loads
since there now more implied dereferenceable bytes.

We already annotate whether llvm.amdgcn.implicitarg.ptr is known to be
unused. Start using it to avoid allocating the implicit arguments if
unneeded.

This is another attempt to make function-local declarations
(like static variables, structs/classes and other) be correctly
emitted within a lexical (bracketed) block.

This patch proposes to move emission of global variables, types,
imported entities, etc from DwarfDebug::beginModule() to DwarfDebug::endModule().
Effectively, this changes nothing but the order of debug entities which
will be as follows:
* subprograms (including related context, local variables/labels,
  local imported entities; related types can be created as a part of
  the emission of local entities of an abstract subprogram);
* global variables (including related context and types);
* retained types and enums;
* non-local-scoped imported entities;
* basic types;
* other types left (as a part of local variables attributes emission).

Note that the order of emitted compile units may also be changed as now we emit
units that contain subprograms first and then all other non-empty units.

The motivation behind this change is the following:
(1) DwarfDebug::beginModule() is run at the very beginning of backend's pipeline,
    from this time IR can be significantly changed by target-specific passes.
    If it happens for debug metadata of global entities, those changes will not
    be reflected in the emitted DWARF.
(2) imported subprogram names should refer to an abstract subprogram if it exists,
    but it isn't known in DwarfDebug::beginModule() (it's possible to make some
    guesses based on location info, but it's not quite reliable);
(3) aforementioned entities if they are scoped within a bracketed block
    (subject of D113741) couldn't be emitted in DwarfDebug::beginModule()
    (they need parent emitted first). Another problem is if to try to gather
    some information about local entities and defer their emission
    (till subprogram's processing or DwarfDebug::endModule()) all the gathered
    details might be irrelevant / invalid by the time the entities are being
    emitted (because of (1)).

Swap AIC and IC neighbouring in pipeline. This looks more natural and even
almost has no effect for now (three slightly touched tests of test-suite). Also
this could be the first step towards merging AIC (or its part) to -O2 pipeline.

After several changes in AIC (like D108091, D108201, D107766, D109515, D109236)
there've been observed several regressions (like PR52078, PR52253, PR52289)
that were fixed in different passes (see D111330, D112721) by extending their
functionality, but these regressions were exposed since changed AIC prevents IC
from making some of early optimizations.

This is common problem and it should be fixed by just moving AIC after IC
which looks more logically by itself: make aggressive instruction combining
only after failed ordinary one.

Add an -enable-merge-functions option to allow testing of function
merging as it will actually happen in the optimization pipeline.
Based on that add a test where we currently produce two identical
functions without merging them due to incorrect pass scheduling
under the new pass manager.

Currently it's hidden inside ClangTidyDiagnosticConsumer,
so it's hard to know it exists.

Given that there are multiple uses of globs in clang-tidy,
it makes sense to have these classes publicly available
for other use cases that might benefit from it.

Also, add unit test by converting the existing tests
for GlobList into typed tests.
