BTF: Support for BTF_KIND_FLOAT
Add BTF_KIND_FLOAT, a new BTF type kind which has recently stabilized in
the linux kernel [1]. This kind is used for encoding floating point
types, and is of particular use when generating BTF for some s390
arch-specific kernel headers.
Also update some BTF tests which previously used floating point types to
check correct behavior for types with no BTF representation.

include/ChangeLog:
* btf.h (struct btf_type): Update bit usage comment.
(BTF_INFO_KIND): Update bit mask.
(BTF_KIND_FLOAT): New define.
(BTF_KIND_MAX): Update.
gcc/ChangeLog:
* btfout.c (get_btf_kind): Support BTF_KIND_FLOAT.
(btf_asm_type): Likewise.
gcc/testsuite/ChangeLog:
* gcc.dg/debug/btf/btf-float-1.c: New test.
* gcc.dg/debug/btf/btf-function-3.c: Use different unrepresentable type.
* gcc.dg/debug/btf/btf-struct-2.c: Likewise.
* gcc.dg/debug/btf/btf-variables-2.c: Likewise.
