Ayshe Kuran	55ec2ba4bc	Fix PR47973: Addressing integer division edge case with INT_MIN ... Adjustment to integer division in int_div_impl.inc to avoid undefined behaviour that can occur as a result of having INT_MIN as one of the parameters.

Ayke van Laethem	4d41df6482	[builtins] Support architectures with 16-bit int ... This is the first patch in a series to add support for the AVR target. This patch includes changes to make compiler-rt more target independent by not relying on the width of an int or long.

Fangrui Song	b541196eb4	[builtins] Make __umodsi3/__udivdi3/__umoddi3 standalone (shift and subtract) ... @kamleshbhalui reported that when the Standard Extension M (Multiplication and Division) is disabled for RISC-V, `__udivdi3` will call __udivmodti4 which will in turn calls `__udivdi3`. This patch moves __udivsi3 (shift and subtract) to int_div_impl.inc `__udivXi3`, optimize a bit, add a `__umodXi3`, and use `__udivXi3` and `__umodXi3` to define `__udivsi3` `__umodsi3` `__udivdi3` `__umoddi3`.
