2021-05-02target/mips: Move TCG source files under tcg/ sub directoryPhilippe Mathieu-Daudé
To ease maintenance, move all TCG specific files under the tcg/ sub-directory. Adapt the Meson machinery. The following prototypes: - mips_tcg_init() - mips_cpu_do_unaligned_access() - mips_cpu_do_transaction_failed() can now be restricted to the "tcg-internal.h" header.

2021-05-02target/mips: Move IEEE rounding mode array to new source filePhilippe Mathieu-Daudé
restore_msa_fp_status() is declared inlined in fpu_helper.h, and uses the ieee_rm[] array. Therefore any code calling restore_msa_fp_status() must have access to this ieee_rm[] array. kvm_mips_get_fpu_registers(), which is in target/mips/kvm.c, calls restore_msa_fp_status. Except this tiny array, the rest of fpu_helper.c is only useful for the TCG accelerator. To be able to restrict fpu_helper.c to TCG, we need to move the ieee_rm[] array to a new source file.

2020-06-09target/mips: fpu: Refactor conversion from ieee to mips exception flagsAleksandar Markovic
The original coversion function is used for regular and MSA floating point instructions handling. Since there are some nuanced differences between regular and MSA floating point exception handling, provide two instances of the conversion function, rather than just a single common one. Inline both instances of this function instances for the sake of performance. Improve variable naming in surrounding code for clarity.
