    • RISC-V: Disable -msave-restore for shared libraries. · a169f358 
      This was noticed while trying to test -msave-restore support.  The
save/restore routines use the alternate return register t0/x5 which is
clobbered by the PLT header, so we can't use them in shared libraries.
This patch disables -msave-restore when -fpic (and -mplt), and emits a
warning if the user explicitly turned on -msave-restore.

	gcc/
	* config/riscv/riscv.c (riscv_option_override): If -msave-restore
	and -fpic and -mplt then disable -msave-restore and warn.

    • compile, runtime: permit anonymous and empty fields in C header · 4a140826 
          
    Permit putting structs with anonymous and empty fields in the C header
    file runtime.inc that is used to build the C runtime code.  This is
    required for upcoming 1.13 support, as the m struct has picked up an
    anonymous field.
    
    Doing this lets the C header contain all the type descriptor structs,
    so start using those in the C code.  This cuts the number of copies of
    type descriptor definitions from 3 to 2.

    • Optimize std::to_chars · 7259a9d5 
      Bunch of micro optimizations for std::to_chars:
* For base == 8 replacing the lookup in __digits table with arithmetic
computations leads to a same CPU cycles for a loop (exchanges two movzx
with 3 bit ops). However this saves 129 bytes of data and totally avoids
a chance of cache misses on __digits.
* For base == 16 replacing the lookup in __digits table with
arithmetic computations leads to a few additional instructions, but
totally avoids a chance of cache misses on __digits (- ~9 cache misses
for worst case) and saves 513 bytes of const data.
* Replacing __first[pos] and __first[pos - 1] with __first[1] and
__first[0] on final iterations saves ~2% of code size.
* Removing trailing '\0' from arrays of digits allows the linker to
merge the symbols (so that "0123456789abcdefghijklmnopqrstuvwxyz" and
"0123456789abcdef" could share the same address). This improves data
locality and reduces binary sizes.
* Using __detail::__to_chars_len_2 instead of a generic
__detail::__to_chars_len makes the operation O(1) instead of O(N). It
also makes the code two times shorter.

In sum: this significantly reduces the size of a binary (for about 4KBs
only for base-8 conversion), deals with latency (CPU cache misses)
without changing the iterations count and without adding costly
instructions into the loops.

	* include/std/charconv (__detail::__to_chars_8)
	__detail::__to_chars_16): Replace array of precomputed digits with
	arithmetic operations to avoid CPU cache misses. Remove zero
	termination from array of digits to allow symbol merge with generic
	implementation of __detail::__to_chars. Replace final offsets with
	constants. Use __detail::__to_chars_len_2 instead of a generic
	__detail::__to_chars_len.
	(__detail::__to_chars): Remove zero termination from array of digits.
	(__detail::__to_chars_2): Leading digit is always '1'.
