Crash fixes and small improvements to inline asm. ( #1756 )
...
* codegen: LLVMConstInlineAsm is deprecated.
* codegen: replace commas in asm constraint strings by pipes as required by LLVM.
* ir: enforce usage of '=' constraint modifier for inline assembly outputs.
Others are not currently supported and this was just asserted alter in `ir_render_asm`.
* asm: forbid comptime_int/floats as inputs in favor of explicitely sized constants.
Fixes a crash due to comptime_int/floats having no type_ref.
* asm: handle inputs with integers of <8 or non power of 2 bitsize.
We widen them to the next highest power of two.

better string literal caching implementation
...
We were caching the ConstExprValue of string literals,
which works if you can never modify ConstExprValues.
This premise is broken with `comptime var ...`.
So I implemented an optimization in ConstExprValue
arrays, where it stores a `Buf *` directly rather
than an array of ConstExprValues for the elements,
and then similar to array of undefined, it is
expanded into the canonical form when necessary.
However many operations can happen directly on the
`Buf *`, which is faster.
Furthermore, before a ConstExprValue array is expanded
into canonical form, it removes itself from the string
literal cache. This fixes the issue, because before an
array element is modified it would have to be expanded.
