peter klausler	4cbfd93a59	[flang] Make `TypeParamInquiry` monomorphic ... Change the expression representation TypeParamInquiry from being a class that's templatized on the integer KIND of its result into a monomorphic representation that results in a SubscriptInteger that can then be converted. This is a minor simplification, but it's worth doing because it is believed to also be a work-around for bugs in the MSVC compiler with overload resolution that affect the expression traversal framework.

peter klausler	8f0f9eaddf	[flang] Fix CHARACTER length folding problem ... Do not rewrite LEN(x) or x%len to the expression that specifies the length of x when that length is not a constant expression. Its value may have changed since the value of the expression was first captured in the definition of the object.

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.

Tim Keith	76d71354db	[flang] Add message formatting for std::int64_t ... There is no printf formatting string for std::int64_t. Instead we have to cast to std::intmax_t and use `%jd`. This change simplifies that by automatically converting std::int64_t to std::intmax_t when formatting messages.
