62a02d25b6 Add .nop assembler directive 
Implement the '.nop SIZE[, CONTROL]' assembler directive, which emits
SIZE bytes filled with no-op instructions.  SIZE is absolute expression.
The optional CONTROL byte controls how no-op instructions should be
generated.  If the comma and @var{control} are omitted, CONTROL is
assumed to be zero.

For Intel 80386 and AMD x86-64 targets, CONTROL byte specifies the size
limit of a single no-op instruction.  The valid values of CONTROL byte
are between 0 and 8 for 16-bit mode, between 0 and 10 for 32-bit mode,
between 0 and 11 for 64-bit mode.  When 0 is used, the no-op size limit
is set to the maximum supported size.

2 new relax states, rs_space_nop and rs_fill_nop, are added to enum
_relax_state, which are similar to rs_space and rs_fill, respectively,
but they fill with no-op instructions, instead of a single byte.  A
target backend must override the default md_generate_nops to generate
proper no-op instructions.  Otherwise, an error of unimplemented .nop
directive will be issued whenever .nop directive is used.

76db0a2e17 Also disallow global alias of common symbol 
We can't create alias of common symbol.  Local alias of common symbol has
been disallowed.  But global alias of common symbol is disallowed when the
common symbol is seen first and silently dropped otherwise.  This patch
disallows alias of common symbol in all cases.

8860a416a2 replace some raw xmalloc / xrealloc with the XNEW* macros 
This increases consistancy of how we allocate memory, and always casting the
result to the proper type.  It also helps make sure we get any use of sizeof on
the result type correct.

35c1a43964 gas: don't get confused by .asci{i,z} after .struct 
While not allowed, this certainly shouldn't result in confusing the
programmer (by skipping lines in unexpected ways): Without returning,
demand_empty_rest_of_line() (at the end of the function) will demand
the _next_ line to be empty, and without the conditional we would
ignore the next line.

2e57ce7b14 More fallout from "Allow symbol and label names to be enclosed in double quotes" 
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.

696025802e gas: allow labeling of CFI instructions 
When runtime patching code (like e.g. done by the Linux kernel) there
may be cases where the set of stack frame alterations differs between
unpatched and patched code. Consequently the corresponding unwind data
needs patching too. Locating the right places within an FDE, however,
is rather cumbersome without a way to insert labels in the resulting
section. Hence this patch introduces a new directive, .cfi_label. Note
that with the way CFI data gets emitted currently (at the end of the
assembly process) this can't support local FB- and dollar-labels.

e74211b660 gas: avoid bogus warnings in false branches of conditional 
The construct being added to the cond.s test case otherwise triggered
both the "missing closing ..." and the "stray ..." (twice) warnings in
_find_end_of_line(). As that code fragments suggests, this is needed to
support (include) files that can be used for both assembler .include
and compiler #include directives.
