This allows using command line flags to lowere from GPU to SPIR-V. The
pass added is only for testing/example purposes. Most uses cases will
need more fine-grained control on setting workgroup sizes for kernel
functions.

Summary:
Partners have requested the ability to configure more parts of Scudo
at runtime, notably the Secondary cache options (maximum number of
blocks cached, maximum size) as well as the TSD registry options
(the maximum number of TSDs in use).

This CL adds a few more Scudo specific `mallopt` parameters that are
passed down to the various subcomponents of the Combined allocator.

- `M_CACHE_COUNT_MAX`: sets the maximum number of Secondary cached items
- `M_CACHE_SIZE_MAX`: sets the maximum size of a cacheable item in the Secondary
- `M_TSDS_COUNT_MAX`: sets the maximum number of TSDs that can be used (Shared Registry only)

Regarding the TSDs maximum count, this is a one way option, only
allowing to increase the count.

In order to allow for this, I rearranged the code to have some `setOption`
member function to the relevant classes, using the `scudo::Option` class
enum to determine what is to be set.

This also fixes an issue where a static variable (`Ready`) was used in
templated functions without being set back to `false` every time.

Costs currently fall back to scalar generic intrinsic calls

These are just pass-throughs to the source operand - we can't assume that ANY_EXTEND(splat) will still be a splat though.

Update logic for reserving VGPR for SGPR spills. A CSR VGPR being reserved for
SGPR spills could be clobbered if there were no free lower VGPR's available.
Create a stack object so that it will be spilled in the prologue. Also

Previously this flag was just ignored. If set, set the
IMAGE_DLL_CHARACTERISTICS_NO_SEH bit, regardless of the normal safeSEH
machinery.

In mingw configurations, the safeSEH bit might not be set in e.g. object
files built from handwritten assembly, making it impossible to use the
normal safeseh flag. As mingw setups don't generally use SEH on 32 bit
x86 at all, it should be fine to set that flag bit though - hook up
the existing GNU ld flag for controlling that.

The previous approach of adding up the file sizes of the
component sections ignored the fact that the sections did not have to be
contiguous in the file. As such, it was underestimating the true size.

I discovered this issue because `codesign` checks whether `__LINKEDIT`
extends to the end of the file. Since we were underestimating segment
sizes, this check failed.

We found a case where Typedef Name Declarations were not being added
correctly when importing builtin types. This exposed the need for a
TypedefNameDecl visitor so these types can be added by RecordDecl and

This code is covered by the ASTImporterTest cases that use the implicit
struct __NSConstantString_tag definitions.
