This change adds support for software floating point operations for Sparc targets.
This is the first in a set of patches to enable software floating point on Sparc. The next patch will enable the option to be used with Clang.

Coverage mapping data is organized in a sequence of blocks, each of which is expected
to be aligned by 8 bytes. This feature is used when reading those blocks, see
VersionedCovMapFuncRecordReader::readFunctionRecords(). If a misaligned covearge
mapping data has more than one block, it causes llvm-cov to fail.

* Reworks the CVSymbolTypes.def to work similarly to TypeRecords.def.
* Moves some enums from SymbolRecords.h to CodeView.h to maintain
consistency with how we do type records.
* Generalize a few simple things like the record prefix
* Define the leaf enum and the kind enum similar to how we do with tyep
records.

I don't yet fully understand the meaning of these data strcutures,
but at least it seems that their sizes and types are correct.
With this change, we can read publics streams till end.

We currently don't represent get_local and set_local explicitly; they
are just implied by virtual register use and def. This avoids a lot of
clutter, but it does complicate stackifying: get_locals read their
operands at their position in the stack evaluation order, rather than
at their parent instruction. This patch adds code to walk the stack to
determine the precise ordering, when needed.

Thanks to Paul Robinson for pointing this out!

This patch moves the expansion of WIN_ALLOCA pseudo-instructions
into a separate pass that walks the CFG and lowers the instructions
based on a conservative estimate of the offset between the stack
pointer and the lowest accessed stack address.
The goal is to reduce binary size and run-time costs by removing
calls to _chkstk. While it doesn't fix all the code quality problems
with inalloca calls, it's an incremental improvement for PR27076.

As discovered in PR27758, GDB does not fully support the DWARF 4 format.
This patch ensures we always emit bitfields in the DWARF 2 when tuning for GDB.

When processing inline asm that contains errors, make sure we can recover
gracefully by creating an UNDEF SDValue for the inline asm statement before
returning from SelectionDAGBuilder::visitInlineAsm. This is necessary for
consumers that don't exit on the first error that is emitted (e.g. clang)
and that would assert later on.
Fixes PR24071.

This adds support for all the MachO *_command structures. The load_command payloads still are not represented, but that will come next.

Summary:
Colons can appear in Windows paths after drive letters. Both colon and
semicolon are valid characters in filenames, but neither are very
common. Semicolon seems just as good, and makes the test pass on
Windows.

This bug was introduced in r269728 and is the likely cause of many stage 2 ubsan bot failures.
I'll add a test in a follow-up commit assuming this fixes things properly.

... for AddRec's in loops for which SCEV is unable to compute a max
tripcount. This is the NUW variant of r269211 and fixes PR27691.
(Note: PR27691 is not a correct or stability bug, it was created to
track a pending task).
