8f5753ba9f Fix normalization of right-shifted BigInt at CT 
The pointer value for the `digits` field was being treated as if it were
a limb.

fix thread local variables for non- position independent code 
This fixes comes thanks to Rich Felker from the musl libc project,
who gave me this crucial information:

"to satisfy the abi, your init code has to write the same value
to that memory location as the value passed to the [arch_prctl]
syscall"

This commit also changes the rules for when to build statically
by default. When building objects and static libraries, position
independent code is disabled if no libraries will be dynamically
linked and the target does not require position independent code.

add docs for assembly and fix global assembly parsing 
Previously, global assembly was parsed expecting it to have
the template syntax. However global assembly has no inputs,
outputs, or clobbers, and thus does not have template syntax.
This is now fixed.

This commit also adds a compile error for using volatile
on global assembly, since it is meaningless.

Fix generation of comptime slices

first class support for compiling C code 
New CLI parameter: --c-source [options] [file]

It even works with `--cache on` when there are transitive dependencies.

Instead of `builder.addCExecutable`, use `builder.addExecutable` and pass
`null` for the root source file. Then use `builder.addCSourceFile`,
which takes the path to the C code, and a list of C compiler args.
Be sure to linkSystemLibrary("c") if you want libc headers to be
available.

Merge TestStep into LibExeObjStep. That was long overdue.

better field access of types which have one possible value 
* When you do field access of a type which only has one possible
   value, the result is comptime-known.
 * StorePtr instructions which operate on pointers to types which
   only have one possible value, the result is a comptime no-op.
