9902b604cb Fix generation of container initializers
The code creates temporary ConstExprValue with global_refs set to
nullptr and that's carried over to the final value. Doing so prevents
the deduplication mechanism to work correctly, causing all sorts of
runtime crashes.

Fixes #1636
Fixes #1608 (Even though it was already fixed by #1991)

9ec4ccc68f Do not invoke UB in BigInt shr operations
Shifting a value of type T by an amount that's greater or equal to the
size of the type itself is UB.

@sizeOf returns 0 for comptime types
This defines `@sizeOf` to be the runtime size of a type, which means
that it is zero for types such as comptime_int, type, and (enum
literal).

1a2e02e267 fixed #2356
const_ptr_pointee_unchecked did not take into account that if the
pointer is zero sized, then const_val->data.x_ptr.special would be
ConstPtrSpecialInvalid. This commit fixes this by also checking
that the child type of the pointer only have one possible value
and just returns that value.

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.
