Jean Perier f1fa3b7f6e [flang] AMAX0, MIN1... rewrite to MAX/MIN: make result conversion explicit

Summary:
This patch changes speficic extremum functions rewrite to generic MIN/MAX.
It applies to AMAX0, AMIN0, AMAX1, AMIN1, MAX0, MIN0, MAX1, MIN1, DMAX1,
and DMIN1.

- Do not re-write specific extremums to MAX/MIN in intrinsic Probe and let
folding rewrite it and introduc the conversion on the MIN/MAX result.
- Also make operand promotion explicit in MIN/MAX folding.

For instance, after this patch:
AMAX0(int8, int4) is rewritten to REAL(MAX(int8, INT(int4, 8)))

All this care is to avoid rewritting it to MAX(REAL(int8), REAL(int4))
that may not always be numerically equivalent to the first rewrite.
