`format` does not properly handle the `ll` (long long) specifier about asymptote

[johncbowman]

Thanks for reporting this. Actually, the int type in Asymptote is supposed to be the highest precision native integer (normally 64 bits) so for consistency, format should always enforce ll. In fact, an explicit 'll' doesn't really make sense from the point of view of the Asymptote machine (which, except for the bitwise functions AND, OR, XOR, NOT, CLZ, and CTZ pretends to be unaware of bit representations). So the desired behavour should be:

format("%x",intMax);
7ffffffffffffffd

format("%x",intMin);
8000000000000000

format("%d",intMax);
9223372036854775805

format("%d",intMin);
-9223372036854775808

In fact the current version of Asymptote tries to turn 1 trillion dollars into a huge loss:
format("$%'d",1000000000000);
$-727,379,968

With commit 488d809, the correct result is produced:
format("$%'d",1000000000000);
$1,000,000,000,000
