We used to have a big switch statement over the type categories and kinds
inside Minloc/Maxloc. After D133051 the switch grew bigger, and this
changed inlining decisions made by GCC (the build compiler). Some of the
simple methods stopped being inlined, and this caused slight performance
regression in Polyhedron/gas_dyn2. This change adds separate entries
for real/integer data types to let them be optimized separately.

std::numeric_limits<__float128>::max/lowest return 0.0, so recreate
value of FLT128_MAX ourselves to avoid using quadmath.h's FLT128_MAX
that is currently causes warnings with GCC -Wpedantic.

When passing a scalar .FALSE. as the MASK argument to MAXLOC, we were getting
bad memory references. We were falling into the code intended when the MASK
argument was missing.
I fixed this by checking for a scalar MASK with a .FALSE. value and
setting the result to all zeroes in that case. I also added tests for
MAXLOC and MINLOC with scalar values of .TRUE. and .FALSE. for the MASK
argument.
I also special cased situations where the MASK argument is a scalar with
a .TRUE. value and passed along a nullptr in such cases.
Along the way, I eliminated the unused "chars" argument from the constructor
for ExtremumLocAccumulator.

Add a header-only implementation of Briggs & Torczon's fast small
integer set data structure to flang/include/flang/Common, and use
it in the runtime to manage a pool of Fortran unit numbers with
recycling. This replaces the bit set previously used for that
purpose. The set is initialized on demand with the negations of
all the NEWUNIT= unit numbers that can be returned to any kind
of integer variable.
For programs that require more concurrently open NEWUNIT= unit
numbers than the pool can hold, they are now allocated with a
non-recycling counter. This allows as many open units as the
operating system provides.
Many of the top-line comments in flang/unittests/Runtime had the
wrong path name. I noticed this while adding a unit test for the
fast integer set data structure, and cleaned them up.

Move the closure of the subset of flang/runtime/*.h header files that
are referenced by source files outside flang/runtime (apart from unit tests)
into a new directory (flang/include/flang/Runtime) so that relative
include paths into ../runtime need not be used.
flang/runtime/pgmath.h.inc is moved to flang/include/flang/Evaluate;
it's not used by the runtime.

Port external-io test to use GTest. Remove Runtime tests directory.
Rename RuntimeGTest directory to Runtime.
This is the last in a series of patches which ported tests from the old
flang/unittests/Runtime test directory to use GTest in a temporary
unittest directory under flang/unittests/RuntimeGTest. Now that all the
tests in the old directory have been ported to use GTest, the old
directory has been removed and the GTest directory has been renamed to
flang/unittests/Runtime.
