=== Context ===
This patch is part of a patch series to add support for ARMv8-R
architecture. Its purpose is to keep the distinction between
architecture feature bits and extension ones after parsing has occured.
=== Motivation ===
This distinction is necessary to allow the Tag_CPU_arch build attribute
value to be exactly as per the architecture of the selected CPU. With
mixed architecture and extension feature bit, it is impossible to find
an architecture with an exact match of feature bit and the build
attribute value logic must then select the closest match which might not
be the right architecture. The previous patch in the patch series makes
the distinction possible when parsing -mcpu and .cpu directives but the
distinction gets lost after. Similarly feature bits contributed by
extensions in -march or .arch_extensions directive are mixed together
with architecture extensions.
=== Patch description ===
The patch adds new feature bit pointer for extension feature bits.
Information from the parsing regarding extensions can then be kept
separate in those. This requires adapting arm_parse_extension to deal
with two feature bits, allowing the architecture bits to be marked as
const. It also requires extra care when setting cpu_variant and
selected_cpu because the extension bits are optional since there might
not be any extension in use.
Note that contrary to cpu feature bits, the extension feature bits are
made read/write and are always dynamically allocated. This allows to
unconditionally free them in arm_md_post_relax added for this occasion,
thereby fixing a longstanding memory leak when arm_parse_extension was
invoked (XNEW of ext_fset without corresponding XDELETE).
Introduction of arm_md_post_relax is necessary to only free the
extension feature bits after aeabi_set_attribute_string has been called
for the last time.

Some of the TC_START_LABEL implementations need to adjust the end of
the symbol, when a colon doesn't mean a label definition. That means
they need access to nul_char both the restore the NUL location (it may
be a quote rather than a colon) and to store the new nul_char. Others
need adjusting to step over a potential trailing quote.
