When cmodel=extreme, since the symbol address is obtained through four
instructions,
errors may occur in some cases during linking. Therefore, in order to ensure
that
the instructions for obtaining the symbol address are together, macro
instructions
are used to obtain the symbol address when cmodel=extreme.

There are some problems with the test case changes, I will fix them in
the v2 version.

LoongArch: Add the macro implementation of mcmodel=extreme.
LoongArch: When the code model is extreme, the symbol address is
obtained through macro instructions regardless of the value of
-mexplicit-relocs.
