* trans-array.c (gfc_trans_create_temp_array): Remove use of the
function argument. Always generate code for negative extent.
Simplify said code.
* trans-array.h (gfc_trans_create_temp_array): Change prototype.
* trans-expr.c (gfc_conv_function_call): Remove use of last argument
of gfc_trans_create_temp_array.
* trans-intrinsic.c (gfc_conv_intrinsic_array_transfer): Likewise.

* trans-intrinsic.c (gfc_conv_intrinsic_repeat): Evaluate
arguments only once. Generate check that NCOPIES argument is not
negative.

(gfc_simplify_char): ICE if extract_int fails. Error if
value < 0 or value > 255.

* simplify.c (convert_mpz_to_unsigned): New function.
(convert_mpz_to_signed): New function, largely based on
twos_complement().
(twos_complement): Removed.
(gfc_simplify_ibclr): Add conversions to and from an
unsigned representation before bit-twiddling.
(gfc_simplify_ibset): Same.
(gfc_simplify_ishftc): Add checks for overly large
constant arguments, only check the third argument if
it's present, carry over high bits into the result as
appropriate, and perform the final conversion back to
a signed representation using the correct sign bit.
(gfc_simplify_not): Removed unnecessary masking.
