This patch changes the default types of argc/argv so it's no longer a
uint64_t in all systems, instead, it's now a uintptr_t, which fixes
crashes in 32-bit systems that expect 32-bit types. This patch also adds
two uintptr_t types (EnvironType and AuxEntryType) for the same reason.
The patch also adds a PgrHdrTableType type behind an ifdef that's
Elf64_Phdr in 64-bit systems and Elf32_Phdr in 32-bit systems.
This patch changes the instruction in set_thread_ptr from ld to mv,
as rv32 doesn't have the ld instruction, and mv is supported by both
rv32 and rv64.

This patch is large, but is almost entirely just adding casts to calls
to syscall_impl. Much of the work was done programatically, with human
checking when the syntax or types got confusing.

This patch mostly renames files so it better reflects the function they declare.

This patch standardizes the error messages when a syscall is not
available to be in the format: "ABC and DEF syscalls are not available."

Summary:
The changes in D146184 made the integration tests use the inhereted
dependencies from the startup code like a normal target. For the AArch64
target this resulted in the threads depenency not being pulled in
because it was not present in the original code.
Fixes#61355. The __dso_handle decl was introduced incorrectly into the startup
objects during the integration test cleanup which moved the integration tests
away from using an artificial sysroot to using -nostdlib. Having it in the
startup creates the duplicate symbol error when one does not use -nostdlib.
Since this is an integration test only problem, it is meaningful to keep it in
the integration test anyway.

Also, added riscv64 startup code for static linking which is used
by the integration tests. Functions from the C standard threads
library have been enabled.

The test binaries are built like any other executable but with two
additional linker options -static and -nostdlib.

Instead of using a custom target to copy the startup object file to a
file with the desired name, a normal object library with a special
property is used.
Follow up patches will do more cleanup wrt how the startup objects are
used in integration tests.

We currently put everything in one single archive libc.a which breaks in
certain situations where the compiler drivers expect libm.a also. With
this change, we separate out libc.a and libm.a functions as is done
conventionally and put them in two different static archives.
One will now have to build two targets, `libc` and `libm` which produce
`libc.a` and `libm.a` respectively. Under default build, one still builds only
one target named `libc` which produces `libllvmlibc.a`.
