In order to debug a failing python test, you need to debug Python
instead of the wrapper. For a while I've been adding and removing this,
but I think it could be useful for everyone.

The Emscripten OS provides a definition of __EMSCRIPTEN__, and also that it
supports iprintf optimizations.
Also define small_printf optimizations, which is a printf with float support
but not long double (which in wasm can be useful since long doubles are 128
bit and force linking of float128 emulation code). This part is based on
sunfish's https://reviews.llvm.org/D57620 (which can't land yet since
the WASI integration isn't ready yet).

This is on by default, since on many platforms and configurations
libc++abi.a gets statically linked into shared libraries and/or
PIE executables.
This change is a followup to https://reviews.llvm.org/D60005 which
allows us to default to PIC code, but disable this if needed (for
example on WebAssembly where PIC code its currently compatible with
static linking).

This change is in preparation for the addition of new target
operand flags for new relocation types. Have a symbol type as part
of the flag set makes it harder to use and AFAICT these are serving
no purpose.

Fixed the inability to properly rebind the testing allocator, by making the
inner alloc_impl type a plain struct and making the operations templates. Before
rebind failed to compile complaining that a alloc_impl<T>* was not convertible
to an alloc_impl<U>*.
This enables the test to pass for MSVC++ once we provide the strong guarantee
for the copy assignment operator.

In fact we don't even need a loop at all. I backed out the bug fix this was testing for and verified that this new case hit the same issue.
This should stop D59626 from deleting some of this code by realizing it was dead due to the loop.

We should overall stop using these, but the uppercase name didn't
work. Any feature string is converted to lowercase, so these

Summary:
Reorder the fields in both to use padding more efficiently, and add more
comments on the purpose of the fields.
Replace `std::vector<SectionChunk*> AssociativeChildren` with a
singly-linked list. This avoids the separate vector allocation to list
associative children, and shrinks the 3 pointers used for the typically
empty vector down to 1.
In the end, this reduces the sum of heap allocations used to link
browser_tests.exe with NO PDB by 13.10%, going from 2,248,728 KB to
1,954,071 KB of heap. These numbers exclude memory mapped files, which
are of course a significant factor in LLD's memory usage.

Summary:
Before this patch, we would only ever throw an exception if the badbit
was set on the stream. The Standard is currently very unclear on how
exceptions should be propagated and what error flags should be set by
the input stream operations. This commit changes libc++ to behave under
a different (but valid) interpretation of the Standard. This interpretation
of the Standard matches what other implementations are doing.
I will submit a paper in San Diego to clarify the Standard such that the
interpretation used in this commit (and other implementations) is the only
possible one.

This function should only be called with instructions that are really convertible. And all
convertible instructions need to be handled by the switch. So nothing should use the default.

X86FixupLEAs just assumes convertToThreeAddress will return nullptr for any instruction that isn't convertible.
But the code in convertToThreeAddress for X86 assumes that any instruction coming in has at least 2 operands and that the second one is a register. But those properties aren't guaranteed of all instructions. We should check the instruction property first.

We were using the number of Matchables rather than the number of rows in the converter table.
This only matters for a few of the targets where the number of matchables is more than 255, but the number of converters is less than 255. Many of the targets have more than 256 converters. So already required a uint16_t.

This adds partial instruction selection support for llvm.aarch64.stlxr. It also
factors out selection for G_INTRINSIC_W_SIDE_EFFECTS into its own function. The
new function removes the restriction that the intrinsic ID on the
G_INTRINSIC_W_SIDE_EFFECTS be on operand 0.
Also add a test, and add a GISel line to arm64-ldxr-stxr.ll.

moveAttrFromListToList only makes sense when moving an attribute to a list with
a pool that's either equivalent, or has a shorter lifetime. Therefore, using it
to move a ParsedAttr from a declarator to a declaration specifier doesn't make
sense, since the declaration specifier's pool outlives the declarator's. The
patch adds a new function, ParsedAttributes::takeOneFrom, which transfers the
attribute from one pool to another, fixing the use-after-deallocate.

A recent patch to LLD started emitting information about import modules.
These are represented as compile units in the PDB, but with no
additional debug info. This was confusing the native pdb reader, who
expected that the debug info stream be present.
This should fix failing tests on the Windows bots.
