target-mips: Fix helper and tests for dot/cross-dot product instructions

Helper function for dpa_w_ph, dpax_w_ph, dps_w_ph and dpsx_w_ph incorrectly
defines halfword vector elements as unsigned values. This results in wrong
output which is not triggered in the tests as they also follow this logic....

target-mips: Replace macros by inline functions

The macros RESTORE_ROUNDING_MODE and RESTORE_FLUSH_MODE silently used
variable env from their callers. Using inline functions with env passed
as a function argument is more transparent.

This modification was proposed by Peter Maydell....

target-mips: Allow DSP access to be disabled once enabled.

Clear the DSP hflags at the start of compute_hflags. Otherwise access
is not properly disabled once enabled.

target-mips: Use EXCP_SC rather than a magic number

From the discussion on the ML [1], the exception limit defined by
magic number 0x100 is actually EXCP_SC defined in cpu.h. Replace the
magic number with EXCP_SC. Remove "#if 1 .. #endif" as well.

target-mips: Make repl_ph to sign extend to target-long

The immediate value is 9bits, should sign-extend to 16bits. The return value to
register should sign-extend to target_long, as Richard says, removing an
unnecessary cast works fun.

target-mips: Remove semicolon from macro definition

Macro RESTORE_FLUSH_MODE is similar to RESTORE_ROUNDING_MODE
but included a semicolon.

The code which uses that macro also includes a semicolon,
so the result was an empty statement.

Remove the superfluous semicolon from the macro definition....

target-mips: Fix for helpers for EXTR_* instructions

The change removes some unnecessary and incorrect code for EXTR_S.H.
Further, it corrects the mask for shift value in the EXTR_ instructions. It also
extends the existing tests so they trigger the issues corrected with the change....

target-mips: Fix incorrect reads and writes to DSPControl register

Upper 4 bits of ccond (bits 31..28 ) of DSPControl register are not used in
the MIPS32 architecture. They are used in the MIPS64 architecture. For MIPS32
these bits must be written as zero, and return zero on read....
